I have a kingston "expert mouse", which is a trackball (go figure), that I need to set up for left handed operation as i switch between it and a regular mouse to help reduce fatigue in one hand.

I have only been able to fine an arch wiki page for a logitech trackball based on libinput i think but haven't' been able to get it working. I was able to get it working in XFCE (who'da thunk?) as it had a little pull down to specify the pointing device and then config accordingly. I am really hoping there is something similar hidden in the depths or KDE settings or maybe something I can install.

The arch wiki was a bit confusing to me about the different methods so I am hoping there is a more noobish option.

Thanks in advance!

Nada? Meaning its not possible?

Well it is not KDE or Plasma specific but a setting you need to make manually in the X11 section, as suggested in the Arch wiki. >There is all the information you need, can't really help you more.
