I have two super keys on my keyboard. The left is in large use by Ubuntu and the right has really little use. However the little used Super_r key has minor function which prevents it being used by editors.
So I would like to stop the right Super having any Ubuntu function so I can make it a Super key in Sublime without OS conflict.
How do i disable Ubuntu function without disabling the key for other programs, so that the key is Super for other programs but not Ubuntu.
