The EDT keyboard layout refers to how the editor mapped the numeric keypad
on the VTXXX series of terminals, and OpenVMS and UNIX workstations.

The EDT Keypad may have been arbitrary also, but it was also used by the
KED editor for quite a while before EVE showed up.

With the LK2xx keyboards having a FIND/INSERT/REMOVE/SELECT/PREV/NEXT
cluster, many of the EDT keys have fallen out of use.

The ENTER key on EDT is different than the RETURN key on the typewriter
section of the keyboard.  The Enter key was used to terminate an EDT
command, the RETURN key inserted a line break.

All VT series keyboards had the 4 arrow keys for navigation also.
