The only configuration you need to do is inside Blizzard's key bindings dialog.
Description
CharmKeys is an extremely simple addon, designed to make it easy to mark targets in combat. It allows you to bind keys to assign a raid marker to the unit that is under the mouse cursor, whether it's a unit frame, name plate, or character in the game world. Since it uses the mouseover unit, you don't have to change targets in order to re-mark, vital for a tank or melee DPS.
The same effect can be accomplished with macros, which is why the addon is so extremely tiny. CharmKeys just allows you to save up to 9 macro slots by binding keys directly.
