Using Input Mapping

In This Topic

You can change the keyboard keys that are used to trigger built-in actions to other keys. Actions include navigation, selection, cut, copy, paste, clear, undo, and redo.

There is a complete list of actions in the SpreadActions class.

Using Code

The following example maps keys to actions.
