on my laptop (Lenovo Yoga Slim 7) I have a dedicated keyboard key to switch workspce. But when I use it, it switches only between the 1st ans last one.
I would do it under “Keyboard Shortcuts Preferences” my desktop is mate, but you will have this somewhere too.
There it has change to left workspace and change to right workspace … click on the existing shortcut and reprogram it new with your key and the specific direction key.
