Map/List of commander hotkeys?

I've been looking through the wiki and various threads but haven't found what I'm looking for:
Is there a visual map or compiled list of all the commander hotkeys?
Also, is there a reason I can't see the location names when commanding? It's a pain to try telling people where to go if you haven't memorized all the locations on every map.

It seems like nobody ever wants to command so I thought I'd crack the arthritic knuckles and learn how to not be a total douche in the chair/hive.
