KeyBs

Removes the last key from the key command line. If the key command line is empty, this function will not perform any action.

You should call this function using a "Hot Key" command (as shown in the example below), otherwise the backspace character is placed into the key command line and the command does not execute. A "Hot Key" command is a command that executes as soon as it is placed into the key command line.
