Thanks a lot, it does work! I was thinking there would be a lot of people wanting this functionality and would be a straight forward thing but...
Tuttle, When I turn the mouse keys on there are other things that stops working. For example command + W closes a window when mouse keys is off but when I turn it on this stops working. Also even though I have UN-CHECKED "Ignore trackpad when Mouse keys is on", once I set the mouse keys on, my trackpad stops working.
What am I missing? I am using Mac OS X 10.5.7
Thanks
