Recently my TAB key started acting very strange. At the left end of the line it indents my code normally, which it should also do if I hit TAB anywhere in the line. But now, if I'm in the middle of the line it tries to do a TAGS search. I don't have a tags file and I don't want one, thank you very much.
I'm using Prelude and believe it has to do with Projectile, which I've never used. When I ask emacs what the keybinding of the TAB key is with
C-h k, it lies and says:
It is bound to TAB. (indent-for-tab-command &optional ARG)
When I saw this last week I disabled Projectile mode and that helped but now it doesn't seem to help. How can I find out what's binding this key and get rid of it?
