This small file written in Z80 code turns off the key click for KayPro's.

To use enter "Q<CR>" and the clicking is gone.
To have the clicking back just unplug the keyboard cord and plug it in
again. Not very hi-tech you say ! Well then just put a "0" for the "8" in the
MAC file and re-compile it with M80 and call it "UQ"!

Or just run "UQ".
