API SetMacroSpell

Changes the spell used for dynamic feedback for a macro. SetMacroSpell(index, spell [, target]) or SetMacroSpell(name, spell [, target])

• index: - Index of the macro, using the values 1-36 for the first page and 37-54 for the second.
• name: - Name of a macro.
• spell: - Localized name of a spell to assign.
• target: : UnitId - The unit to assign (for range indication).

• When assigned to an action button, macros can provide dynamic feedback such as range indication, cooldown, and charges/quantity remaining.
• Normally, this dynamic feedback corresponds the action that the macro will take; however, this function directs the macro to provide feedback based on a particular spell instead.
• This only changes the visual cues appearing on the action buttons, but not the actual logic. Clicking an action button executes the macro as written.
