This is a sequel to my first screencast on the same topic. This improved version uses only AutoHotkey to adjust the volume and mute, and it works on Windows XP and Windows 7.
Here’s the screencast. See below for detailed instructions on how to set it up for yourself.
Step 2: Download volume.ahk (shown below) and put it in the Startup folder. To find the Startup folder, click the Start button, then All Programs. Right-click on the Startup folder and click Open.
Step 3: Run volume.ahk by double clicking on it. This is what’s in volume.ahk.
; Volume control (turn master volume up and down with Ctrl-Alt-Up/Down and
; toggle mute with Ctrl-Alt-.)
^!Up::Send {Volume_Up}
^!Down::Send {Volume_Down}
^!.::Send {Volume_Mute}
That’s it. Now you can use these keyboard shortcuts to adjust the volume and toggle mute.
Ctrl-Alt-Up: Increase the volume Ctrl-Alt-Down: Decrease the volume Ctrl-Alt-Period: Mute the volume
