In emacs, Ctrl-Alt-\ means indent the selected region according to style
rules for the type of file being edited (very useful), and Ctrl-Alt-End
does something related to emacs-Lisp programming (less useful, IMO).
Both \ and End are right next to Bksp on my laptop keyboard, but only
the \ is at risk on my desktop keyboard.  Other nearby keys (=, ], and
PgDn) don't have default emacs bindings with Ctrl-Alt, but I suppose a
sophisticated emacs user could bind them to something useful.

Some GNOME keyboard shortcuts use Ctrl-Alt as well.

I'm a GNOME and  emacs user, but I'm not taking sides here, just
responding to the request for information.
