I was a rather puzzled the first time I spotted DWIM in an Emacs interactive command name. Don’t think I remember what the command itself was, but what’s important here is that DWIM stands for do what I mean.

I love DWIM interactive commands. They enable commands to be smarter and thus pack more functionality, without incurring the typical cognitive overhead associated with remembering multiple commands (or key bindings). The Emacs manual does a great job describing DWIM for the comment-dwim command:

The word “dwim” is an acronym for “Do What I Mean”; it indicates that this command can be used for many different jobs relating to comments, depending on the situation where you use it.
