Is there a way to use mouse navigation (system settings > Accessibility > Mouse Navigation) with a keyboard that does not have a numpad? I would like to move the cursor and to click with my keyboard. If I understand correctly that is what mouse navigation does but my keyboard does not have a number pad. Is there some KDE way of emulated a number pad on such a keyboard. I have come across input-remapper but I cannot get it to work (I’m on openSUSE Leap 15.5). I am using mainly X at the moment, but wayland is working pretty well for me, and I would like to move to it so a solution that worked on wayland would be a bonus. I would be grateful for any pointers.
I can tell you that it IS indeed possible, but I cannot tell you if you can achieve that easily under KDE.
You might want to ask the blender community on how that is done, they had that exact functionality running to emulate a number pad on laptops without number pads.
Maybe search the blender handbook for emulate numberpad, not emulate 3rd mouse button. In blender preferences, input, keyboard you can check emulate numpad.
Thanks. In the end I discovered Mouseless https://github.com/jbensmann/mouseless, which can control the mouse with keyboard.
