Re: Keybinding that loops through Major Modes

[Christopher Dimech <dimech@gmx.com>]

I shall explain better then.  In my .texi files I customarily include commands
from other modes or want to use some hooks from other modes (e.g. org-mode).
So even after I load a file with the default mode, I would need to quickly
shift to another mode temporarily, then switch back to normal-mode.
