Automatic Scroll Wheel Speaker Volume Control When Hovering Over the Taskbar

This short tip comes directly from the AutoHotkey documentation for the #If directive. I republish it here for those who haven't had a chance to read all the online documentation. Plus, a while back I added it to my main AutoHotkey script and now use my mouse scroll wheel hovering over the Windows Taskbar as my primary method for controlling speaker volume.


A number of other scripts of this type have appeared in the forum, but I have found none quite so simple and easy-to-use.

The #IfWinActive directive restricts Hotkeys to particular active program windows. However, you'll find many times when expressions prove useful for determining whether or not to activate a Hotkey. As in this example, the Hotkey works only when the mouse cursor hovers over the Taskbar. The following script does this by implementing an #If expression directive which checks the mouse cursor location:

Code: Select all

#If MouseIsOver("ahk_class Shell_TrayWnd")
   WheelUp::Send {Volume_Up}
   WheelDown::Send {Volume_Down}

{  MouseGetPos,,, Win
   Return WinExist(WinTitle . " ahk_id " . Win)
I discuss this code (and other examples of mouse cursor location-sensitive AutoHotkey applications) in Chapter Six of the book AutoHotkey Hotkeys: Tips, Tricks, Techniques, and Best Practices.

Thank you! I've been trying lots of programs to do Volume Control with mouse wheel. None of these programs is perfect. Some does not work well, some requires updates after each major Windows 10 update, some displays ugly popups. Your solution is very simple and effective.
