API SetOverrideBindingSpell

Creates an override binding that casts a spell SetOverrideBindingSpell(owner, isPriority, "key", "spell");

Arguments

 * owner : Frame - The frame this binding "belongs" to; this can later be used to clear all override bindings belonging to a particular frame.
 * isPriority : Boolean - true if this is a priority binding, false otherwise. Both types of override bindings take precedence over normal bindings.
 * key : String - Binding to bind the command to. For example, "Q", "ALT-Q", "ALT-CTRL-SHIFT-Q", "BUTTON5"
 * spell : String - Name of the spell you want to cast when this binding is triggered.

Details

 * Override bindings take precedence over the normal bindings. Priority override bindings take precedence over non-priority override bindings.
 * Override bindings are never saved, and will be wiped by an interface reload.
 * You cannot use this function to clear an override binding; use instead.
