volume

Hi All,

I recently had to replace a keyboard and this one ( GE 98552 ) does not have programmable buttons along the top and I miss the up/down volume buttons. it has 9 special buttons but none for volume and this model is not programmable. DUH!

I am a long-time Delphi programmer but never messed with the multimedia stuff.

Can anyone suggest some code to assign to say the "+" and "-" keys on the numeric pad that will change the volume up and down? I never use those two buttons so I would not be giving up functionality.

Thanks

Frank
