My right hand is temporarily immobilized. I would like to do some minor work in Emacs, mostly in Org-mode, but also some in AUCTeX. Is there some way to ease one-handed work in Emacs such as some mode or particular work flow? For instance I noticed pressing C-x u is easier than C-_ for undoing and that it is easier to mark text with methods involving C-Space than with combinations of S- and movement commands.

I have found http://stackoverflow.com/questions/2391805/how-can-i-remain-productive-with-one-hand-completely-immobilized but that is not what I am asking for. I want to ease whatever little time spent one-handed in Emacs and this is also interesting for situations where there is no injury involved, such as when one hand is occupied. I also do realize I should avoid unnecessary strain.
