Command-Key modified cursor

I implemented tracking rects and used mouseMove to change the cursor 
depending on modifier keys. In this case holding command key is  zoom 
in while command and option is zoom out. It works OK, but pressing 
the command key does not get the correct curser until the mouse 
physically moves again. I tried to find an event for key press, but 
could not find one (command key or option key alone do not generate 
keyDown event). I didn't try cursor rects, but found no indication 
that cursor tracking would update correctly on command or option key 
presses.

Where does one trap an event to change the cursor whenever the mouse 
is within some rectangle and whenever the command or option key are 
pressed or released while in that rectangle?
