Depends on the handset. Try overriding Canvas.keyPressed(), record the 
value received somewhere, like a text log or on the screen, and see what 
value you get when the key is pressed. Then hard-wire that value into 
your code for that handset. J2ME API does not specify a keyPressed() 
value for cancel buttons, but most handsets deliver one anyway. If you 
are not getting keyPressed() events, try adding a Command of type CANCEL 
or BACK to the Displayable; then, you may have to use a CommandListener 
or you may then be able to get keyPressed(). Sometimes a cancel button 
automatically gets mapped to the CANCEL/BACK Command, if any.
