On my Linux system, ed and key.ex pick up the same
key codes, as they should. For me, only Home and End generate
3 codes at once.

wait_key() and get_key() are handled by the
the same routine in the interpreter, with a parameter
indicating if the routine should wait or return -1.

Picking a different key to use instead of Esc
sounds like the easiest thing to do, although Esc
is certainly in a nice position on the keyboard.
