Named World of Warcraft Macro Action
A Named World of Warcraft Macro Action sends a Key Combination configured in the World of Warcraft Macro Library; the key combo itself is assigned in the game, by a generated WoW Addon, to do a specified macro (World of Warcraft only)
The Add optional modifiers options allow you to select modifier keys to send along with the WoW Macro's Key Combination. This helps create and use WoW Macros that use conditions based on the modifier keys held at the time. By default, these boxes will usually be grayed out and unavailable, meaning that the WoW Macro in the library does not allow for additional modifiers.
