Editing WoW:API GetBindingByKey

{{wowapi}}
 local binding = GetBindingByKey(key)

This returns whatever is bound to "key", be it a spell or an action or a click. If there is no binding it returns nil, unlike [[API GetBindingAction]] which returns a blank string.

== Parameters ==
=== Arguments ===
* key (string) - WoW 'key name' of the key to get the binding for, such as an upper case letter like "K"

=== Returns ===
* binding (string) - the full binding command string, which is the name of the action that will be taken
