In my quest for using the computer mouse as little as possible, I thought I had come up with a great idea.
Why not implement a keyboard mouse, using the windows key and arrow keys for navigation.
But then my second thought was, this must already exist.
Sure enough, after some searching on the net, I found this link
Here is the essence of the link in short.
Shift + NumLock to activate numpad as keyboard mouse. 1,2,3,4,6,7,8,9 to navigate ”5” left mouse button ”-” & ”5” right mouse button ”*” & ”5” middle mouse button
It will take some time to get use to, but at least it exists as an alternative.
