Using extra mouse buttons to quickly switch to a task in KDE

I had a bright idea to use my extra 2 mouse buttons to quickly switch to a task in Debian KDE, for example to terminal or browser. Since the mouse is in the palm of your hand most of the time this is quite a bit faster than actually clicking on a task or hitting a key combo on your keyboard.

I started by pinning Konsole and Firefox to taskbar positions 1 and 2 and then went to

System Settings -> Shortcuts -> Plasma -> Activate Task Manager entry 1

Shortcuts like Meta+1, Meta+2 etc already exists so I thought I can simply add an alternative shortcut. Unfortunately, this configurator does not detect the mouse buttons (nothing happens if you click and key is not recorded).

Fortunately, KDE also has a nice feature in your Mouse settings to remap the extra buttons to anything you like in

System Settings -> Input devices -> Mouse -> Re-Bind Additional Mouse Buttons

In there, I simply assigned one button to Meta+1 and the other button to Meta+2. I can see plenty of other useful possibilities like mapping the button to shift through different windows of a task etc.

The mouse I use is Roccat KONE Aimo which also has a third button labeled T3 (and a plus/minus buttons which are bound for DPI sensitivity by default) but T3 does not get picked up by the configurator even after disabling EasyShift (which basically remaps the whole mouse when pressed so all the buttons can have a different function temporarily). The surprising thing is that if I map that button to some functionality like Browser Home (in Windows Roccat driver) it does actually work in a Linux Browser, so I am not sure why KDE Mouse configuratior does not detect this button.

 

Update: I found an alternative way of doing this which also enables T3. On Windows, using the Roccat driver software, assign each mouse button a shortcut. Try to find something that is not used by anything. I ended up with something like alt+ctrl+Page Up/Down/End.

Then in KDE shortcuts, assign an alternative to Meta+1 by clicking the button. This time, the button is recorded as the assigned shortcut.
