Subject: bug#24822: 25.1; [PATCH] Support remapping control X keysym
Date: Sun, 30 Oct 2016 01:53:52 +0200 [thread overview]

There is a number of X keysyms that can be remapped inside Emacs, namely
alt, hyper, meta and super. I found it odd that control is not on the
list (and to a lesser degree, shift), so I wrote a patch to offer it as
additional remappable X keysym. This way one can swap the control and
meta key in Emacs with `(setq x-meta-keysym 'ctrl x-ctrl-keysym 'meta)`.
