CDC's KRONOS also allowed abbreviated commands; I grew quite fond of 
typing "COMMO" for "COMMON" (attach to the system's common area) and "POO" 
for "POOL" (can't remember what that does, and my books are long gone).

Cough cough...  The above sequence was how you broke into KRONOS:

Get the timing right, and you were in supervisor mode (or whatever it was 
called).  I remember when I was in the terminal room happily hacking away,

exclaiming "Security is pffft!".  Terrified, I casually leaned over the
Duckwriter pretending to look for something, to obscure just what I'd been 

I dimly recall that you could log off other users by (somehow) sending
a ^D to their terminal, but I could be confusing that with something
else (this was decades ago).
