Hmmmmm I don't know too much about the custom keyboard buttons. I use HP PCs but I have a KVMA switch. I used to try to program the special buttons but every time I jumped to the other PC it messed it up, so I gave up trying.
AutoIt3 has a very simple command built in to set the wav volume
SoundSetWaveVolume(percent)
It also has some hotkey facilities. The hotkey mechanism isn't as extensive as AutoHotKey but the syntax is easy to understand. It's a pretty good lanuage for a beginner programmer.
You'd use the HotKeySet() function to set the hotkey.
Then in the handler adjust the percentage up or down and
call SoundSetWaveVolume().
Should be less than 20 lines of code even if you set up the tray menu.
Just a matter of which keys HotKeySet() allows you to use.
I'll leave that as an exercise for the reader.
AutoIt3 has a forum
http://www.autoitscr...com/forum/index.php?There are newbies asking for help all the time. Seems
like a pretty easy project to start with. If you get it
to work it will a lot more fun to use it. You could even
stick an icon with your name on it(well initials anyway,) on the thing.
