I am running Virtual Box on a Kubuntu system with the guest OS OpenVMS V9.2.2. A physical VT100 has keys on the keypad that differ from those on a common PC keyboard. The help on VMS from the editor for using the keypad mode does not identify useful info when using a PC keyboard.

There is a display mapping from the VT-100 keyboard keypad keys to the EDT functions.

How do I get the mapping for a PC keyboard?
