Each key is pressed by the finger on the home row that is closest. After reaching a key away from the home row, the finger needs to return to its home row key.

Example: How to Type Letter U
1. Make sure that your fingers are on their home row keys.
2. Move your right index finger from J upwards to U. Your hand may move slightly to make it easier to reach U.
3. Press U with a quick and light touch keeping your hand relaxed.
4. Move the index finger back to its home key J.

The Space Bar
Most people use their right thumb for the Space bar. Left-handed people may find it easier to use their left thumb. Whichever thumb you decide to use, stick with it. Never use both thumbs.
