How do I create a keyboard combination that can be held down to treat the successive mouse moves as if they were three-finger-on-trackpad movements?
So I can hold down e.g. cmd and shift, then move the mouse, and it would be as if I were performing that movement with three fingers, to perform things like
- change spaces
- expose mission control
- show application windows
There are of course already individual keyboard shortcuts for all of the three-finger trackpad actions.
However, these are (often) two-handed keyboard shortcuts.
I would like to configure a left-hand only "modifier", which will then treat my next mouse move as if it were performed with three fingers.
