Hi Rustom,

Maybe this helps (dunno)?
http://www.emacswiki.org/emacs/CategoryReferenceSheet

Or maybe you are looking for an Emacs function that _generates_ cheat sheets?
In that case, `C-h m' and `C-h b' come to mind.  Or if you want to know/print
the bindings of a particular keymap (by name), `C-h M-k' from library
help-fns+.el does that (http://www.emacswiki.org/emacs/help-fns%2b.el).

FWIW - Personally, I've never seen much utility in cheat sheets for Emacs.  I
confess that I did make some for myself when I was a newbie, but I never really
bothered with them after I discovered Emacs's integrated help (`C-h m', `C-h b',
`C-h k', `C-h w', `C-h a', `M-x apropos', etc.).  No doubt the _act of making_
such a sheet manually can help one learn some keys, but beyond that I don't see
much point in them.  Just one opinion, of course.
