I don't really think that is needed. The sendkey command was  
implemented to send real keystrokes. A 'sendkeys' can always be  
simulated using multiple strokes.

You could just create a script/program that converts your command line  
to several 'sendkey' commands. An idea of how to implement that in C  
is attached.

This would be monitor.c. Afaik every handling of the monitor command  
line is done there. I still don't really think it's necessary.
