Answer 1

From the docs for editfield it says,

An editable text field specifically designed for characters entered by holding a key while rolling the trackwheel.

• Behaviour

Adds the ability to hold down a letter and roll to get related characters. The actual characters selected will be based on locale.

Rolling wraps around the list of available characters, once one end of the list is reached.
