I have been using a full-size Mac-compatible keyboard instead of the smaller Apple keyboard which came with my iMac. This full size keyboard (brand name Macally) does not have VOLUME keys, which is a problem when I need to mute the sound level quickly to take a phone call or to talk to someone at my desk. ControllerMate allowed me to assign "F" keys to the functions of VOLUME DOWN, VOLUME UP and MUTE.

I chose to configure F1=VOLUME DOWN, F2=VOLUME UP and F4=MUTE.

(F3=FIND AGAIN in Firefox, so I did not use that key.)

After just a few minutes of head-scratching and fiddling around with ControllerMate, I was able to set up this configuration. The graphic format of ControllerMate is very simple and fun, once you get the hang of it. I am looking forward to using this program to configure other functions, if the need arises.

So far, these new volume keys are working for me. If I have any problems, I will leave another review here.
