This happens to me /all/ the time: start writing a Jira issue report (like this one ) or a wiki page, then realize I made a typo, so hit ctrl-B. I hit this because of the deeply ingrained muscle memory that Emacs has given me. Unfortunately, ctrl-B will royally hose you because it's a shortcut for "browser back". Of course at that point, you've completely lost everything you've been editing and there's no way to get it back. Other shortcuts will do the same thing (ctrl-A too IIRC). I really just want to shut off the keyboard shortcuts all together.
