&kwrite; is a text editor for &kde; allowing you to edit one file at the time per window.

KDE
KWrite
text
editor

## Introduction

&kwrite; is more than a text editor for the &kde; Desktop. It is meant to be a programmer's editor, and could be considered as at least a partial alternative to more powerful editors. It may be best used in conjunction with &konqueror; or &dolphin; for source file browsing for different languages. &kwrite; also works very well as a simple text editor. One of &kwrite;'s main features is the colorized syntax, customized for many different programming languages such as: C/C++, &Java;, Python, Perl, Bash, Modula 2, &HTML;, and Ada.

&kwrite; has a single document interface (SDI) allowing you to edit one file at the time per window.

&kwrite; features two different modes, a simple mode with a straightforward interface and an advanced mode with more features and more extensive menu items. The advanced mode is enabled by checking the option Enable power user mode (&kde; 3 mode) on the Appearance page in &kappname;s settings.

## Some Fundamentals

&kwrite; is very simple to use. Anyone that has used a text editor should have no problems.

### Drag and Drop

&kwrite; uses the &kde; Drag and Drop protocol. Files may be dragged and dropped onto &kwrite; from the Desktop, the filemanager &dolphin;, or some remote &FTP; site opened in one of &dolphin;'s windows.

### Command Line Options

Though &kwrite; may most often be started from the &kde; program menu, or a desktop icon, it can also be opened at the command line prompt of a terminal window. There are a few useful options that are available when doing this.

#### Specify a File

By specifying the path and name of a particular file the user can have &kwrite; open (or create) that file immediately upon startup. This option might look something like the following:

    % kwrite
    /home/myhome/docs/myfile.txt

#### Specify a file on the Internet

The above-mentioned method could even be used to open files on the Internet (if the user has an active connection at the time.) An example of this might look like the following:

    % kwrite
    ftp://ftp.kde.org/pub/kde/README

#### Other Command Line Options

The following command line help options are available

``kwrite` `--help``

  This lists the most basic options available at the command line.

``kwrite` `--help-qt``

  This lists the options available for changing the way &kwrite; interacts with &Qt;.

``kwrite` `--help-kde``

  This lists the options available for changing the way &kwrite; interacts with &kde;.

``kwrite` `--help-all``

  This lists all of the command line options.

``kwrite` `--author``

  Lists &kwrite;'s authors in the terminal window

``kwrite` `-v, --version``

  Lists version information for &Qt;, &kde;, and &kwrite;. Also available through ``kwrite` `-v``

``&kwrite;` `--license``

  Shows license information.

``kwrite` `--stdin``

  Causes &kwrite; to read the document content from STDIN. This is similar to the common option `-` used in many command line programs, and allows you to pipe command output into &kwrite;.

``kwrite` `--encoding` `encoding` `&URL;``

  Causes &kwrite; to use the specified encoding for the document.

``kwrite` `--line` `line` `&URL;``

  Navigate to the specified line after opening the document.

``kwrite` `--column` `column` `&URL;``

  Navigate to the specified column after opening the document.

### Shortcuts

Many of the shortcuts are configurable by way of the Settings menu. By default &kwrite; honors the following shortcuts:

Ins | Toggle between Insert and Overwrite mode. When in insert mode the editor will add any typed characters to the text while pushing along any data to the right of the text cursor. Overwrite mode causes the entry of each character to eliminate the character immediately to the right of the text cursor.
Left Arrow | Move the cursor one character to the left
Right Arrow | Move the cursor one character to the right
Up Arrow | Move the cursor up one line
Down Arrow | Move the cursor down one line
Page Up | Move the cursor up one page
&Alt;Page Up | Previous Bookmark
Page Down | Move the cursor down one page
&Alt;Page Down | Next Bookmark
&Backspace; | Delete the character to the left of the cursor
Home | Move the cursor to the beginning of the line
End | Move the cursor to the end of the line
Delete | Delete the character to the right of the cursor (or any selected text)
&Shift;&Enter; | Insert newline including leading characters of the current line which are not letters or numbers. It is useful &eg; to write comments in the code: At the end of the line // some text press this shortcut and the next line starts already with // . So you do not have to enter the comment characters at the beginning of each new line with comments.

## The Menu Entries

There are different menus and menu items in simple and advanced mode. The advanced mode is enabled by checking the option Enable power user mode (&kde; 3 mode) on the Appearance page in &kappname;s settings.

### The File Menu

&Ctrl;N File New

  This starts a new document in a new and independent editor window.

&Ctrl;O File Open...

  Displays a standard &kde; Open File dialog. Use the file view to select the file you want to open, and click on Open to open it.

File Open Recent

  This is a shortcut to open recently saved documents. Clicking on this item opens a list to the side of the menu with several of the most recently saved files. Clicking on a specific file will open it in &kappname; - if the file still resides at the same location.

&Ctrl;S File Save

  This saves the current document. If there has already been a save of the document then this will overwrite the previously saved file without asking for the user's consent. If it is the first save of a new document the save as dialog (described below) will be invoked.

File Save As...

  This allows a document to be saved with a new file name. This is done by means of the file dialog box described above in the Open section of this help file.

F5 File Reload

  Reloads the active file from disk. This command is useful if another program or process has changed the file while you have it open in &kappname;.

&Ctrl;P File Print...

  Opens a simple print dialog allowing the user to specify what, where, and how to print.

File Export as HTML

  Export your file in &HTML; format so your document can be viewed as a web page. This item is only displayed when the plugin Exporter is loaded.

&Ctrl;W File Close

  Close the active file with this command. If you have made unsaved changes, you will be prompted to save the file before &kappname; closes it.

&Ctrl;Q File Quit

  This will close the editor window, if you have more than one instance of &kappname; running, through the New or New Window menu items, those instances will not be closed.

### The Edit Menu

&Ctrl;Z Edit Undo

  This is used to eliminate or reverse the most recent user action or operation.

&Ctrl;&Shift;Z Edit Redo

  This will reverse the most recent change (if any) made using Undo

&Ctrl;X Edit Cut

  This command deletes the current selection and places it on the clipboard. The clipboard is a feature of &kde; that works invisibly to provide a way to transfer data between applications.

&Ctrl;C Edit Copy

  This copies the currently selected text to the clipboard so that it may be pasted elsewhere. The clipboard is a feature of &kde; that works invisibly to provide a way to transfer data between applications.

&Ctrl;V Edit Paste

  This will insert the contents of the clipboard at the cursor position. The clipboard is feature of &kde; that works invisibly to provide a way to transfer data between applications.

Edit Copy as HTML

  This copies the currently selected text to the clipboard as &HTML;. This item is only displayed when the plugin Exporter is loaded.

&Ctrl;A Edit Select All

  This will select the entire document. This could be very useful for copying the entire file to another application.

&Ctrl;&Shift;A Edit Deselect

  Deselects the selected text in the editor if any.

&Ctrl;&Shift;B Edit Block Selection Mode (Power user mode)

  Toggles Selection Mode. When the Selection Mode is BLOCK, you can make vertical selections, &eg; select column 5 to 10 in lines 9 to 15. The status bar shows the current state of the Selection Mode, either BLOCK or LINE.

Meta&Ctrl;V Edit VI input Mode (Power user mode)

  Switch to a vi-like, modal editing mode. This mode supports the most used commands and motions from vim's normal and visual mode and has an optional vi mode statusbar. This status bar shows commands while they are being entered, output from commands and the current mode.The behavior of this mode can be configured in the Vi Input Mode section of the Editing page in &kappname;'s settings dialog.

Ins Edit Overwrite Mode

  Toggles the Insert/Overwrite modes. When the mode is INS, you insert characters where the cursor is. When the mode is OVR, writing characters will replace the current characters if your cursor is positioned before any character. The status bar shows the current state of the Overwrite Mode, either INS or OVR.

&Ctrl;F Edit Find...

  This opens the incremental search bar at the bottom of the editor window. On the left side of the bar is an icon to close the bar, followed by a small text box for entering the search pattern.

  When you start entering characters of your search pattern, the search starts immediately. If there is a match in the text this is highlighted and the background color of the entry field changes to light green. If the search pattern does not match any string in the text, this is indicated by a light red background color of the entry field and Not found is displayed at the right side of the bar.

  Use the Next or Previous button to jump to the next or previous match in the document.

  You can choose whether the search should be case sensitive. Selecting Match Case will limit finds to entries that match the case (upper or lower) of each of the characters in the search pattern.

  Click on the green arrow icon at the right side of the incremental search bar to switch to the power search and replace bar.

F3 Edit Find Next

  This repeats the last find operation, if any, without calling the incremental search bar.

&Shift;F3 Edit Find Previous

  This repeats the last find operation, if any, without calling the incremental search bar, and searching backwards instead of forwards through the document.

&Ctrl;R Edit Replace...

  This command opens the power search and replace bar. On the upper left side of the bar is an icon to close the bar, followed by a small text box for entering the search pattern.

  You can control the search mode by selecting Plain text, Whole words, Escape sequences or Regular expression from the drop down box.

  If Escape sequences or Regular expression are selected, the Add... menuitem at the bottom of the context menu of the text boxes will be enabled and allows you to add escape sequences or regular expression items to the search or replace pattern from predefined lists.

  Use the Next or Previous button to jump to the next or previous match in the document.

  Enter the text to replace with in the text box labeled Replace and click the Replace button to replace only the highlighted text or the Replace All button to replace the search text in the whole document.

  You can modify the search and replace behavior by selecting different options at the bottom of the bar. Selecting Match Case will limit finds to entries that match the case (upper or lower) of each of the characters in the search pattern. Selection Only will search and replace within the current selection only. The Find All button highlights all matches in the document and shows the number of found matches in a small popup.

  Click on the green arrow icon at the right side of the power search and replace bar to switch to the incremental search bar.

&Ctrl;H Edit Find Selected

  Finds next occurrence of selected text.

&Ctrl;&Shift;H Edit Find Selected Backwards

  Finds previous occurrence of selected text.

&Ctrl;G Edit Go to Line...

  This opens the goto line bar at the bottom of the window which is used to have the cursor jump to a particular line (specified by number) in the document. The line number may be entered directly into the text box or graphically by clicking on the up or down arrow spin controls at the side of the text box. The little up arrow will increase the line number and the down arrow decrease it. Close the bar with a click on the icon on the left side of the bar.

### The Tools Menu

Tools Read Only Mode

  Set the current document to Read Only mode. This prevents any text addition and any changes in the document formatting.

Tools Mode (Power user mode)

  Choose the filetype scheme you prefer for the active document. This overwrites the global filetype mode set in Settings Configure Editor... in the Filetypes tab for your current document only.

Tools Highlighting (Power user mode)

  Choose the Highlighting scheme you prefer for the active document. This overwrites the global highlighting mode set in Settings Configure Editor... for your current document only.

Tools Indentation (Power user mode)

  Choose the style of indentation you want for your active document. This overwrites the global indentation mode set in Settings Configure Editor... for your current document only.

Tools Encoding

  You can overwrite the default encoding set in Settings Configure Editor... in the Open/Save page to set a different encoding for your current document. The encoding you set here will be only valid for your current document.

  Choose your preferred end of line mode for your active document. This overwrites the global end of line mode set in Settings Configure Editor... for your current document only.

Tools Add Byte Mark Order (BOM)

  Checking this action you can explicitly add a byte order mark for unicode encoded documents. The byte order mark (BOM) is a Unicode character used to signal the endianness (byte order) of a text file or stream, for more information see Byte Order Mark.

&Ctrl;Space Tools Invoke Code Completion (Power user mode)

  Manually invoke command completion, usually by using a shortcut bound to this action.

Tools Word Completion (Power user mode)

  Reuse Word Below (&Ctrl; 9) and Reuse Word Above (&Ctrl; 8) complete the currently typed text by searching for similar words backward or forward from the current cursor position. Shell Completion pops up a completion box with matching entries.

&Ctrl;&Shift;O Tools Automatic Spell Checking

  When Automatic Spell Checking is enabled, wrong text is underlined in the document on-the-fly.

Tools Spelling...

  This initiates the spellchecking program - a program designed to help the user catch and correct any spelling errors. Clicking on this entry will start the checker and bring up the speller dialog box through which the user can control the process. There are four settings lined up vertically in the center of the dialog with their corresponding labels just to the left. Starting at the top they are:

  Unknown word:

    Here, the spellchecker indicates the word currently under consideration. This happens when the checker encounters a word not in its dictionary - a file containing a list of correctly spelled words against which it compares each word in the editor.

  Replace with:

    If the checker has any similar words in its dictionary the first one will be listed here. The user can accept the suggestion, type in his or her own correction, or choose a different suggestion from the next box.

  Language:

    If you have installed multiple dictionaries, here you can select which dictionary/language should be used.

  On the right side of the dialog box are 6 buttons that allow the user to control the spellcheck process. They are:

  Add to Dictionary

    Pressing this button adds the Unknown word to the checker's dictionary. This means that in the future the checker will always consider this word to be correctly spelled.

  Suggest

    The checker may list here a number of possible replacements for the word under consideration. Clicking on any one of the suggestions will cause that word to be entered in the Replace with box, above.

  Replace

    This button has the checker replace the word under consideration in the document with the word in the Replace with box.

  Replace All

    This button causes the checker to replace not only the current Unknown word: but to automatically make the same substitution for any other occurrences of this Unknown word in the document.

  Ignore

    Activating this button will have the checker move on without making any changes.

  Ignore All

    This button tells the checker to do nothing with the current Unknown word: and to pass over any other instances of the same word.

    This only applies to the current spellcheck run. If the checker is run again later it will stop on this same word.

  Three more buttons are located horizontally along the bottom of the spellcheck dialog. They are:

  Help

    This invokes the &kde; help system starting at the &kappname; help pages (this document).

  Finished

    This button ends the spellcheck process, and returns to the document.

  Cancel

    This button cancels the spellcheck process, all modifications are reverted, and you will return to your document.

Tools Spelling (from cursor)...

  This initiates the spellchecking program but it starts where your cursor is instead of at the beginning of the document.

Tools Spellcheck Selection...

  Spellchecks the current selection.

Tools Change Dictionary

  Displays a drop down box with all available dictionaries for spellchecking at the bottom of the editor window. This allows easy switching of the spellcheck dictionary &eg; for automatic spellcheck of text in different languages.

&Ctrl;I Tools Indent

  This increases the paragraph's indentation by one step. The size of the step depends on the indentation settings.

&Ctrl;&Shift;I Tools Unindent

  This reduces the paragraph's indentation by one step. The size of the step depends on the indentation settings.

Tools Clean Indentation

  This cleans the indentation for the current selection or for the line the cursor is currently in. Cleaning the indentation ensures that all your selected text follows the indentation mode you choose.

Tools Align

  Causes a realign of the current line or selected lines using the indentation mode and indentation settings in the document.

&Ctrl;D Tools Comment (Power user mode)

  This adds one space to the beginning of the line where the text cursor is located or to the beginning of any selected lines.

&Ctrl;&Shift;D Tools Uncomment (Power user mode)

  This removes one space (if any exist) from the beginning of the line where the text cursor is located or from the beginning of any selected lines.

&Ctrl;U Tools Uppercase

  Put the selected text or the letter after the cursor in uppercase.

&Ctrl;&Shift;U Tools Lowercase

  Put the selected text or the letter after the cursor in lowercase.

&Ctrl;&Alt;U Tools Capitalize

  Capitalize the selected text or the current word.

&Ctrl;J Tools Join Lines

  Joins the selected lines, or the current line and the line below with one white space character as a separator. Leading/trailing white space on joined lines is removed in the affected ends.

Tools Apply Word Wrap

  Apply static word wrapping on all the document. That means that a new line of text will automatically start when the current line exceeds the length specified by the Wrap words at option in the Editing tab in Settings Configure Editor...

If the plugin Insert File is enabled, you will find here an additional menu item Insert File....

### The Settings Menu

Settings Show Statusbar

  When checked, this displays a small bar at the bottom of the editor containing information about the status of the current document. When unchecked the status bar is hidden.

Settings Show Toolbar

  When checked, this displays a movable toolbar containing buttons used to initiate frequently used commands. When unchecked the toolbar is hidden.

Settings Show Path

  When selected, this displays in the titlebar the path (its location in the file system) of the current document. When unchecked the path is hidden.

Settings Configure Editor...

  This menu item opens a dialog whereby several different settings may be adjusted.

Settings Configure Shortcuts...

  This command opens a dialog box whereby the shortcuts may be changed. A display window shows the list of commands (actions) and their assigned shortcuts, alternates and global shortcuts. The Search line above the list window is used to filter the shortcut list. Selecting an action with a &LMB; click (either on the action name or shortcut cell for the default shortcut or on the alternate cell for an alternative) displays the Default and Custom radio buttons below the selected action.

  To assign or change a shortcut click on the None button. Its label changes then to Input, now press the new key combination for the action.

  For example, with the About &kde; action selected in the display window, press the &Ctrl;, &Alt; and the K key on the keyboard. This would mean that anytime you hold down the &Ctrl; and &Alt; buttons and pressed K (while using &kappname;) the About &kde; display box would be called.

  Use the buttons at the bottom of the dialog to set all shortcuts back to their defaults, print the shortcut list or cancel all changes. Click the OK button to close the dialog and accept all changes.

Settings Configure Toolbars...

  This will open the dialog whereby the toolbar configuration may be changed. The user can choose which shortcut buttons should appear on the toolbar. A display window on the left lists the commands available to placed on the toolbar. A display on the right lists those commands already on the toolbar. A set of four arrow buttons between the two displays manipulates the selections. The right pointing arrow places any command selected in the left pane onto the right pane, i.e., it is added to the toolbar. The left arrow does just the opposite, removing any action selected in the right window from the toolbar. The up and down pointing arrows change the position of an action selected in the right window which changes the position of its button in the toolbar.

### The Help Menu

&help.menu.documentation;

## Configure &kappname;

Selecting Settings Configure Editor... from the menu brings up the Configure Editor dialog box. This dialog can be used to alter a number of different settings. The settings available for change vary according to which category the user chooses from a vertical list on the left side of the dialog. By means of three buttons along the bottom of the box the user can control the process.

You may invoke the Help system, accept the current settings and close the dialog by means of the OK button, or Cancel the process. The categories Appearance, Fonts & Colors, Editing, Open/Save and Extensions are detailed below.

### Appearance

Word Wrap
  Dynamic Word Wrap

    If this option is checked, the text lines will be wrapped at the view border on the screen.

  Dynamic word wrap indicators (if applicable)

    Choose when the Dynamic word wrap indicators should be displayed.

  Align dynamically wrapped lines to indentation depth:

    Enables the start of dynamically wrapped lines to be aligned vertically to the indentation level of the first line. This can help to make code and markup more readable.

    Additionally, this allows you to set a maximum width of the screen, as a percentage, after which dynamically wrapped lines will no longer be vertically aligned. For example, at 50%, lines whose indentation levels are deeper than 50% of the width of the screen will not have vertical alignment applied to subsequent wrapped lines.

Borders
  Show folding markers (if available)

    If this option is checked, the current view will display marks for code folding, if code folding is available.

  Show icon border

    If this is checked, you will see an icon border on the left hand side. The icon border shows bookmark signs for instance.

  Show line numbers

    If this is checked, you will see line numbers on the left hand side.

  Show scrollbar marks

    If this option is checked the current view will show marks on the vertical scrollbar. These marks will for instance show bookmarks.

Sort Bookmarks Menu

  These options are only displayed, if Enable power user mode (&kde; 3 mode) in the next section is checked.

  By position

    The bookmarks will be ordered by the line numbers they are placed at.

  By creation

    Each new bookmark will be added to the bottom, independently from where it is placed in the document.

Advanced

  Enable power user mode (&kde; 3 mode)

    Switch between simple and advanced mode. Changing this mode affects only newly opened / created documents. In &kappname; a restart is recommended.

  Show indentation lines

    If this is checked, the editor will display vertical lines to help identifying indent lines.

  Highlight range between selected brackets

    If this is enabled, the range between the selected matching brackets will be highlighted.

### Fonts & Colors

This section of the dialog lets you configure all fonts and colors in any color scheme you have, as well creating new schemes or deleting existing ones. Each scheme has settings for colors, fonts and normal and highlight text styles.

&kappname; will preselect the currently active scheme for you, if you want to work on a different scheme start by selecting that from the Schema combobox. With the New and Delete button you can create a new scheme or delete existing ones.

At the bottom of the page you can select the Default schema for &kappname;.

#### Colors

Text Area Background
  Normal text

    This is the default background for the editor area, it will be the dominant color on the editor area.

  Selected text

    This is the background for selected text. The default is the global selection color, as set in your &kde; color preferences.

  Current line

    Set the color for the current line. Setting this a bit different from the Normal text background helps to keep focus on the current line.

  Bookmark

    This combobox lets you set overlay colors for various mark types. The color is mixed into the background color of a marked line, so that a line with more marks or a marked line that is current has a background that is a mix of more colors. The mark colors are also used if you enable display of scrollbar marks.

Additional Elements
  Left border background

    This color is used for the marks, line numbers and folding marker borders in the left side of the editor view when they are displayed.

  Line numbers

    This color is used to draw the line numbers on the left side of the view when displayed.

  Bracket highlight

    This color is used to draw the background of matching brackets.

  Word wrap markers

    This color is used to draw a pattern to the left of dynamically wrapped lines when those are aligned vertically, as well as for the static word wrap marker.

  Tab and space markers

    This color is used to draw white space indicators when enabled.

  Spelling mistake line

    sets the color of the line that is used to indicate spelling mistakes.

#### Fonts

Here you can choose the font for the schema. You can choose from any font available on your system, and set a default size. A sample text displays at the bottom of the dialog, so you can see the effect of your choices.

#### Normal Text Styles

The normal text styles are inherited by the highlight text styles, allowing the editor to present text in a very consistent way, for example comment text is using the same style in almost all of the text formats that &kappname; can highlight.

The name in the list of styles is using the style configured for the item, providing you with an immediate preview when configuring a style.

Each style lets you select common attributes as well as foreground and background colors. To unset a background color, rightclick to use the context menu.

#### Highlighting Text Styles

Here you can edit the text styles used by a specific highlight definition. The editor preselects the highlight used by your current document. To work on a different highlight, select one in the Highlight combobox above the style list.

The name in the list of styles is using the style configured for the item, providing you with an immediate preview when configuring a style.

Each style lets you select common attributes as well as foreground and background colors. To unset a background color, rightclick to use the context menu. In addition you can see if a style is equal to the default style used for the item, and set it to that if not.

You will notice that many highlights contain other highlights represented by groups in the style list. For example most highlights import the Alert highlight, and many source code formats imports the Doxygen highlight. Editing colors in those groups only affects the styles when used in the edited highlight format.

### Editing

#### General

Tabulators
  Insert spaces instead of tabulators

    When this is enabled the editor will insert a calculated number of spaces according to the position in the text and the `tab-width` setting when you press the &Tab; key.

  Highlight tabulators

    When this is enabled &kappname; will display a small dot as a visual representation of tabulator characters.

    This also causes dots to be drawn to indicate trailing white space. This will be fixed in a future version of &kappname;

  Tab width

    If the Insert spaces instead of tabulators option is selected this entry determines the number of spaces with which the editor will automatically replace tabs.

Static Word Wrap

  Word wrap is a feature that causes the editor to automatically start a new line of text and move (wrap) the cursor to the beginning of that new line. &kappname; will automatically start a new line of text when the current line reaches the length specified by the Wrap Words At: option.

  Enable static word wrap

    Turns static word wrap on or off.

  Show static word wrap markers (if applicable)

    If this option is checked, a vertical line will be drawn at the word wrap column as defined in the Settings Configure Editor... in the Editing tab. Please note that the word wrap marker is only drawn if you use a fixed pitch font.

  Wrap words at:

    If the Enable static word wrap option is selected this entry determines the length (in characters) at which the editor will automatically start a new line.

Misc
  Remove trailing spaces

    &kappname; will automatically eliminate extra spaces at the ends of lines of text.

  Highlight trailing spaces

    &kappname; will highlight extra spaces at the ends of lines of text.

  Auto brackets

    When the user types a left bracket ([, (, or {) &kappname; automatically enters the right bracket (}, ), or ]) to the right of the cursor.

  Copy/Cut the current line if no selection

    If this option is enabled and the text selection is empty, copy and cut action are performed for the line of text at the actual cursor position.

  Allow scrolling past the end of the document

    This option lets you scroll past the end of the document. This can be used to vertically center the bottom of the document, or put it on top of the current view.

#### Cursor & Selection

Text Cursor Movement
  Smart home and smart end

    When selected, pressing the home key will cause the cursor to skip white space and go to the start of a line's text.

  Wrap cursor

    When on, moving the insertion cursor using the Left and Right keys will go on to previous/next line at beginning/end of the line, similar to most editors.

    When off, the insertion cursor cannot be moved left of the line start, but it can be moved off the line end, which can be very handy for programmers. When this option is chosen, moving the cursor with the arrow keys off the end of a line (to the right) causes it to jump down to the beginning of the next line. Likewise when the cursor is moved past the beginning of a line (to the left) it jumps up to the end of the preceding line. When this option is not selected, moving the cursor right past the end of a line merely causes it to continue horizontally in the same line and trying to move it left past the beginning does nothing.

  PageUp/PageDown moves cursor

    This option changes the behavior of the cursor when the user presses the Page Up or Page Down key. If unselected the text cursor will maintain its relative position within the visible text in &kappname; as new text becomes visible as a result of the operation. So if the cursor is in the middle of the visible text when the operation occurs it will remain there (except when one reaches the beginning or end.) With this option selected, the first key press will cause the cursor to move to either the top or bottom of the visible text as a new page of text is displayed.

  Autocenter cursor (lines):

    Sets the number of lines to maintain visible above and below the cursor when possible.

Text Selection Mode
  Normal

    Selections will be overwritten by typed text and will be lost on cursor movement.

  Persistent

    Selections will stay even after cursor movement and typing.

#### Indentation

Default Indentation mode:

  Select the automatic indentation mode you want to use as default. It is strongly recommended to use `None` or `Normal` here, and use filetype configurations to set other indentation modes for text formats like C/C++ code or &XML;.

Indentation Properties
  Indentation width:

    The indentation width is the number of spaces which is used to indent a line. If the option Insert spaces instead of tabulators on the General tab in the Editing page is disabled, a &Tab; character is inserted if the indentation is divisible by the tab width.

  Keep Extra Spaces

    If this option is disabled, changing the indentation level aligns a line to a multiple of the width specified in Indentation width.

  Adjust indentation of code pasted from the clipboard

    If this option is selected, pasted code from the clipboard is indented. Triggering the Undo action removes the indentation.

Indentation Actions
  Backspace key in leading blank space unindents

    If this option is selected, the &Backspace; key decreases the indentation level if the cursor is located in the leading blank space of a line.

  Tab key action (if no selection exists)

    If you want &Tab; to align the current line in the current code block like in emacs, make &Tab; a shortcut to the action Align.

    Always advance to the next tab position

      If this option is selected, the &Tab; key always inserts white space so that the next tab position is reached. If the option Insert spaces instead of tabulators on the General tab in the Editing page is enabled, spaces are inserted; otherwise, a single tabulator is inserted.

    Always increase indentation level

      If this option is selected, the &Tab; key always indents the current line by the number of character positions specified in Indentation width.

    Increase indentation level if in leading blank space

      If this option is selected, the &Tab; key either indents the current line or advances to the next tab position. If the insertion point is at or before the first non-space character in the line, or if there is a selection, the current line is indented by the number of character positions specified in Indentation width. If the insertion point is located after the first non-space character in the line and there is no selection, white space is inserted so that the next tab position is reached: if the option Insert spaces instead of tabulators on the General tab in the Editing page is enabled, spaces are inserted; otherwise, a single tabulator is inserted.

#### Auto Completion

General
  Auto Completion enabled

    If enabled, a word completion box automatically pops up during typing showing a list of text entries to complete the current text under the cursor.

Minimal word length to complete

  While typing text, the word completion searches for words in the document starting with the already typed text. This option configures the minimal amount of characters that are needed to make the word completion active and pop up a completion box.

#### Vi Input Mode

General
  Use the VI Input mode

    When selected, the vi input mode will be enabled when opening a new view. You can still toggle the vi input mode on/off for a particular view in the Edit menu.

  Let VI commands override Kate shortcuts

    When selected, vi commands will override &kate;'s built-in commands. For example: &Ctrl;R will redo, and override the standard action (showing the search and replace dialog).

  Hide the VI mode status bar

    By default, an extra status bar will be used when the Vi input mode is enabled. This status bar shows commands while they are being typed and messages/errors produced by Vi commands.

    Checking this option will hide this extra status line.

Key Mapping

  Key mapping is used to change the meaning of typed keys. This allows you to move commands to other keys or make special keypresses for doing a series of commands.

  Example:

  F2 -> I-- &Esc;

  This will prepend I-- to a line when pressing F2.

#### Spellcheck

These configuration options are described in the documentation for the &systemsettings; module Spell Checker.

### Open/Save

#### General

File Format
  Encoding:

    This defines the standard encoding to use to open/save files, if not changed in the open/save dialog or by using a command line option.

  Encoding Detection

    Select an item from the drop down box, either to disable autodetection or use Universal to enable autodetection for all encodings. But as this may probably only detect utf-8/utf-16, selecting a region will use custom heuristics for better results. If neither the encoding chosen as standard above, nor the encoding specified in the open/save dialog, nor the encoding specified on command line match the content of the file, this detection will be run.

  Fallback Encoding

    This defines the fallback encoding to try for opening files if neither the encoding chosen as standard above, nor the encoding specified in the open/ save dialog, nor the encoding specified on command line match the content of the file. Before this is used, an attempt will be made to determine the encoding to use by looking for a byte order marker at start of file: if one is found, the right unicode encoding will be chosen; otherwise encoding detection will run, if both fail fallback encoding will be tried.

  End of line:

    Choose your preferred end of line mode for your active document. You have the choice between &UNIX;, DOS/&Windows; or Macintosh.

  Automatic end of line detection

    Check this if you want the editor to autodetect the end of line type. The first found end of line type will be used for the whole file.

  Enable byte order marker

    The byte order mark is a special sequence at the beginning of unicode encoded documents. It helps editors to open text documents with the correct unicode encoding. For more information see Byte Order Mark.

Automatic Cleanups on Load/Save
  Remove trailing spaces

    The editor will automatically eliminate extra spaces at the ends of lines of text while loading/saving the file.

#### Advanced

Folder Config File
  Search depth for config file:

    The editor will search the given number of folder levels upwards for &kappname; config file and load the settings line from it. Further information about these hidden folder config files you find in the article The File .kateconfig.

Backup on Save

  Backing up on save will cause &kappname; to copy the disk file to <prefix><filename><suffix> before saving changes. The suffix defaults to ~ and prefix is empty by default.

  Local files

    Check this if you want backups of local files when saving.

  Remote files

    Check this if you want backups of remote files when saving.

  Prefix

    Enter the prefix to prepend to the backup file names.

  Suffix

    Enter the suffix to add to the backup file names.

#### Modes & Filetypes

This page allows you to override the default configuration for documents of specified mimetypes. When the editor loads a document, it will try if it matches the file masks or mimetypes for one of the defined filetypes, and if so apply the variables defined. If more filetypes match, the one with the highest priority will be used.

Filetype:

  The filetype with the highest priority is the one displayed in the first drop down box. If more filetypes were found, they are also listed.

  New

    This is used to create a new filetype. After you click on this button, the fields below get empty and you can fill the properties you want for the new filetype.

  Delete

    To remove an existing filetype, select it from the drop down box and press the Delete button.

Properties of current filetype

  The filetype with the highest priority is the one displayed in the first drop down box. If more filetypes were found, they are also listed.

  Name:

    The name of the filetype will be the text of the corresponding menu item. This name is displayed in the Tools Filetypes

  Section:

    The section name is used to organize the file types in menus. This is also used in the Tools Filetypes menu.

  Variables:

    This string allows you to configure &kappname;'s settings for the files selected by this mimetype using &kappname; variables. You can set almost any configuration option, such as highlight, indent-mode, encoding, etc.

    For a full list of known variables, see the manual.

  Highlighting:

    If you create a new file type, this drop down box allows you to select a filetype for highlighting.

  Indentation Mode:

    The drop down box specifies the indentation mode for new documents.

  File extensions:

    The wildcards mask allows you to select files by filename. A typical mask uses an asterisk and the file extension, for example `*.txt; *.text`. The string is a semicolon-separated list of masks.

  MIME types:

    Displays a wizard that helps you easily select mimetypes.

  Priority:

    Sets a priority for this file type. If more than one file type selects the same file, the one with the highest priority will be used.

### Extensions

The Plugins tab lists all available plugins and you can check those you want to use. Click on the Information button to open the About dialog of this plugin.

Once a configurable plugin is checked, the Configure button is enabled and you can click it in order to configure the highlighted plugin.

#### Editor Component Plugins

AutoBrace

  The autobrace plugin supersedes the &kate; internal Auto Brackets feature. It automatically inserts a closing brace } at the beginning of the next line after ending a line with an opening one { and pressing the &Enter; key.

Data Tools

  Enables data tools like thesaurus and spell check (if installed). Data tools are only available when text is selected, or when the right mouse button is clicked over a word. If no data tools are offered even when text is selected, you need to install them. Some data tools are part of the &koffice; package. If this plugin is enabled and data tools are installed, additional items appear at the end of the context menu.

Exporter

  This command allows you to export the current document with all highlighting information into a HTML document using File Export as HTML. Additionally you can use Edit Copy as HTML to copy the currently selected text as HTML to the system clipboard.

IconInserter

  The icon inserter plugin is only of use for &kde; developers: It adds an item Insert KIcon-Code into the context menu of the editor. If activated, the &kde;'s icon chooser opens (showing application icons, action icons &etc;..). If you click on it, the file name without file extension will be inserted as text. Useful only for setting icons via &kde;'s framework through the KIcon() class.

Insane (not ZEN) HTML coding (light edition)

  A plugin, which does zen-coding like selector completion. For more information see Zen Coding.

Insert File

  This plugin allows you to insert any readable file at the cursor position. If enabled, the Tools menu has an additional menu item Insert File.
