title: how can i get out of vi editor when esc won't work?
body: <p>I am using vi editor for UNIX.  Sometimes I am experiencing an issue with getting out of vi editor, where I go to press esc then type ":wq" or "q!" to quit, but it is not escaping.  vi editor just enters weird symbols/characters and I can't get out. What do I do to escape and exit when esc won't escape?</p>
