My suggestion is to move Item Link keybinds from “left control+click” & “left shift+click” to “right control/shift+click” or some other non combat critical location on the keyboard.
All too often I bump control and shift during combat and click something “far away” in terms of finger reach (ie elite skill) with the mouse. Instead of activating the skill I clicked, I link the skill in chat. Subsequently, every button I press afterward goes into chat (with shift click) preventing any kind of movement, skill activation, etc and more often than not, results in my death.
Something that is not combat critical, should not be in the main finger placement locations on the keyboard (ie left half of the keyboard should be reserved for only combat critical functions). Further, all key actions should be customizable with the ability to disable.
