I've posted control-lock.el to the emacswiki:
http://www.emacswiki.org/cgi-bin/emacs-en/ControlLockIt is sort of like caps-lock but for the control key. You type a sequence to enable it and it behaves as though you're holding control down until you type ' to exit.
I'm interested in getting some feedback. I've wanted to implement this for a long time and am finding it very useful so far.
Two problems I've noticed: The default key to enable it (C-,) doesn't work in a console. I'm thinking M-l might be a decent alternative key. And the way I currently show it as being enabled (changing the cursor to an underscore) I'm guessing doesn't work
in terminal mode either. Any suggestions about a better way to show that it's enabled?
