Rebind ^C in Vim to also undo current insert op

15:44:34 <tyrmored> is there already an insert mode binding that cancels
    the current insert operation entirely?
15:44:53 <tyrmored> (and returns you to normal mode)
15:45:09 <paradigm> I think you want either <esc> or ctrl-c
15:45:12 <jamessan> <C-c>u
15:45:31 <paradigm> then u, yes
15:45:33 <tyrmored> jamessan: yeah, see, i have <C-c> bound to <C-c>u,
    which is great
15:45:41 <tyrmored> but i was wondering if i'm repeating a binding that
    already exists
15:45:46 <jamessan> nope
15:45:51 <tyrmored> great
