If you plan to have the keyboard cover attached most of the time you will be fine. If you install the surface Linux kernal the touch screen will work but only as a click or click and drag. Things like scrolling/zooming don’t work well.

These things work better in GNOME/KDE but honestly with a keyboard and touchpad/mouse how often would you do this?

I have replaced autohotkeys with https://github.com/espanso/espanso

It does everything I need it to, although I am not sure if it can do the mouse button things you need

To get touch scrolling to work in FF you need to be using wayland. I had the same issue on my Surface pro.

I ended up switching to Gnome, then Plasma for this as Mint did not have any Wayland support at the time.

I have really been enjoying the “Linux User Space” podcast recently
