Wow, I'm really glad this topic is at least being talked about. For a long time I've felt that learning a bunch of 'new' keyboard commands for a new game was such a waste of time when you are basically just playing/flying the same type of thing, ie. airplanes, ect...
The technology industry has standards for communication between devices like computer protocols and such, but it seems there has always been a big hole in the communication between the devices/computers and humans. Microsoft has many standards for the keystrokes to use Windows and their Office applications, so using one or the other you still use the same standardized key command to do the same thing. Like Ctrl-O to Open, Ctrl-S to Save, Ctrl-x, c, and v to Cut, Copy and Paste.
Wouldn't be great if there were standards in the gaming industry for common commands so we don't have to remember them all? Keep this going...
