I do this too, but having just this morning read Jacob Rus's amazing
articles on Cocoa Keybindings [1], one could potentially override
cmd-up to be insert mark, go to beginning of document.  Then if you
want to jump back you can use go to mark.  That would then work in
every cocoa application.

The incremental search in every app, and the Emacs ctrl-u repeating
thing are amazing.  I only tried out Emacs for two days, and even in
that short time I got addicted to ctrl-u, ctrl-v and alt-v.
