Starting Over in VIM using e!

I haven’t posted a trick in a while, so here’s a good one to know.

Ever start working on a file in command mode and then hit the caps key without realizing it.  Wham! All sorts of un-expected things can happen before you know it.  What do you do then? You could use q! to exit without saving, then start over, but there is a more graceful way now.

Enter e!

This will rollback ALL changes to the edited file without having to exit VIM.
