A quick tip for people with multiple monitors and a Wacom tablet. You can setup your function keys on the side of the tablet to switch the mapping area.
First you’ll need to go to System Preferences > Wacom Tablet > Tools > Grip Pen. Set your “Screen Area” to your first monitor.
Now go to Tools > Functions – and the Express Keys tab. Pick a key and select “Display Toggle”. Now try hitting your key. The cursor should now switch to your second monitor. You might need to hit the key twice to go to monitor 2, and once to go to monitor 1.
