Mapping volume, mute, play, pause, etc. I've seen this topic asked a few times and the solution usually appears to be use HID macros with AutoHotkey. However I find that a the SoundSet and Send {Volume_Down} in AutoHotkey change the volume of the media player, not the system.
There are keycodes for volume, 173 mute, 174 volume down, 175 volume up. Is it possible to get HIDmacros to send a keypress using the keycodes? I've googled but can't find anything about doing this with VB script sendkeys.
