Replays the last key sequence (except for the last key, which would execute the command). This function is useful when a command is to be repeated. To call this function from the keyboard, use a Hot Key "*" (asterisk) command, otherwise the KeyReplay() function itself is replayed.
Number of characters to subtract before replay. Default value is 1.
0 (zero) if successful, otherwise an error is returned.
If the previous contents of the key command line were:
"START ABC ENTER"
! Replays "START ABC".
