GT.M permits the use of the VMS command line editor at the Direct Mode prompt and during M READs from a terminal. The VMS line editor allows cursor positioning using the <CTRL> key, edit keypad and function keys. Also, it allows toggling between insert and overstrike modes. The command line editing feature is optional; by default VMS has command line editing turned on.

For more information regarding the VMS command line editor, refer to the VMS Guide to Using VMS.
