Being an Emacs user, I wouldn't mind Control-G as a shortcut to deactivate LB since sometimes it's easier for me to type than Escape or Command-. Also, in Emacs and vim (and Unix tty-based input in general), Control-[ is equivalent to Escape. Not sure how it behaves relative to the Cocoa Text System
; doesn't seem to be assigned to cancelOperation:
, like Escape is, with default key bindings
. Also don't know if LB does or can make use of those key bindings.
