I like this idea a lot. The name "guihints" is a bit strange though, perhaps "uihints" or "controlhints" would be better. The current graphics look good to me. Perhaps some guidelines of how to combine them (eg the angstrom example) would be nice, I mean a standard way to denote simultaneous keypresses, consequent keypresses, etc.
One way to use these hints would be to list the keys that are used followed by an explanation of what they do. Another way would be to show the entire keyboard, with the useful buttons highlighted, and their function shown by means of text balloons or small pictograms. This latter method gives a clearer mental picture in my opinion, because the button locations are much more evident.
