Can it in fact be bound to a non-mouse event?
If I thought it could then I would not have filed this bug.

emacs -Q

Evaluate (global-set-key "\C-o" 'tear-off-window), then try C-o.
I get this error:

command-execute: tear-off-window must be bound to an event with parameters

Same thing (naturally) if I bind a keyboard key to the alias.

If I'm missing something and this can be bound to keyboard keys then please let 
me know how and close the ticket.
