Swapping caps-lock and control was one of the best decisions I made when starting on Emacs, first item on Steve Yegge's list - http://sites.google.com/site/steveyegge2/effective-emacs
Does anyone have similar experiences?
You can't be to thin, have too much money or enough control keys. :-)
(There is always capitalize-region. Or I can change back, if I need to write a lot of upper case, which is very unusual.)
