For example:
initial_define_key (control_x_map, Ctl('X'), "exchange-point-and-mark");
I haven't extended these to allow the initializing code to bind
function keys and mouse events; since they are called by many files,
I'd have to fix lots of callers, and nobody right now would be using
the new functionality, so it seems like a waste of time. But there's
no technical reason not to. -JimB */
