- Send Custom Key
- Show Status Window
- Close Connection
- Hide Toolbar Buttons

## VNCViewer Context Menu

File Transfer... (Hotkey `CTRL+ALT+F7`)
  Open the file transfer dialog window.
Chat... (Hotkey `CTRL+ALT+F8`)
  Open the chat dialog window.
Show/Hide Toolbar (Hotkey `CTRL+ALT+F9`)
  Show or hide the VNCViewer toolbar.
Disable/Enable Remote Input and Monitor
  Disable keyboard and mouse input as well as the monitor on the remote computer.
Connection options... (Hotkey `CTRL+ALT+F6`)
  Open the connection option dialog window.
Connection info
  Open the connection info window.
Request screen refresh
  Redraw the screen in VNCViewer. Sometimes the display in VNCViewer misses updates or becomes corrupted. A screen refresh can then insure that VNCViewer's display and remote computer's display are in sync.
View only
  Disables sending mouse and keyboard events from the VNCViewer to the remote computer.
Various screen size options
  Full screen mode (hotkey `CTRL+ALT+F12`) displays the remote screen on the entire screen of your display. Together with a hidden toolbar this feels like sitting in front of the remote computer.
  Scaled viewer mode displays the scaled remote screen in a window with a user defined size.
  Scaled server mode generates less network traffic from server side and uses a pixel blending algorithm to optimize the display.
  Fuzzy screen mode combines Server and Viewer scaling to provide reasonable visual comfort and speed even over very slow connections.
  Autoscaling mode scales the view to fit the viewer screen.
  Normal screen mode (hotkey `CTRL+F11`) displays the remote screen 1:1.
Full/256 Colors
  Change the color depth of the screen.
Send various key combinations
  Send `CTRL+ALT+DEL` (hotkey `CTRL+ALT+F4`), `CTRL+ESC` (this opens the start menu), `CTRL+Key Down`, `CTRL+Key Up`, `ALT+Key Down` or `ALT+Key Up`.
New connection...
  Start a new connection.
Save connection info as... (Hotkey `CTRL+ALT+F5`)
  Save the options and settings of the active connection in a file.
About VNC Viewer...
  See version and licencing information of VNCViewer.

## Additional Hotkeys

Pressing ALT or CTRL send ALT/CTRL directly to the VNCServer, as if the user selected "CTRL DOWN/CTRL UP/ALT DOWN/ALT UP" from the system menu.

When `SCROLL-LOCK` is activated, all key combinations (except `CTRL+ALT+DEL`) are directly sent to the remote computer:

- Instead of switching applications on the client side, `ALT+TAB` is sent to the VNCServer.
- Instead of opening the start menu on the client side, `CTRL+ESC` is sent to the VNCServer.
- Instead of opening the system menu on the client side, `ALT+SPACE` is sent to the VNCServer.
- Pressing `Break/Pause` key toggles Full-Screen mode on or off.
- Pressing `PRINT-Screen` key requests a full screen update (same as selecting "Request Screen Refresh" from the system menu)

All the above can be disabled by turning the `SCROLL-LOCK` key off.
