Re: Current mode command discovery

[Alfred M. Szmidt]

I (~20 YEARS AGO) HACKED EMACS ON A TEKTRONIX 4010 TO ALLOW ME TO DRAW
VECTOR GRAPHICS ON  THE DISPLAY FROM EMACS USING A  LOGO / TURTLE LIKE
LANGUAGE -- WHILE IT HAD A SHIFT KEY, IT ONLY WORKED FOR THE FIRST ROW
OF KEYS SINCE ALL LETTERS WHERE UPPER CASE.  IT DID NOT HAVE AN ESCAPE
KEY, YOU HAD TO TYPE CONTROL SHIFT K X TO GET M-X.

SO YOU MIGHT BE RIGHT IN THAT  MAYBE IT IS ACTUALLY M-X <LOWER CASE X>
THAT IS  UNTYPABLE ON THE  ANY TERMINAL ...   BUT LETS NOW  SHIFT THIS
