>I don't use Vim much now because I work a lot in Windows, and Vim got me into the habit of hitting escape when I was through entering text, but escape cancels the input in a lot of programs. However, I still use it in the shell or when I need to make certain global edits.

some people discourage the use of the Esc key and prefer to use Ctrl-c instead. I'd recommend to disable it and force to use the Ctrl-c combo. I did it and completely forgot about the Esc key(actually I find it more comfortable)
