This mod modifies the MacroFrame to add a total of 84 macros in a scrollable frame. It also has an lua editbox associated with each macro for advanced scripting (as seen in the screenshot).

The lua editbox is extended scripting to call in a macro, Example:

Put this in the editbox,

function Test()
Addmessage('Sweet')
end

And call it in the macro,

/script Test();

will display on the screen, sweet

To open MegaMacro type /macro, /megamacro, keybinding, or go into the default chat window ChatMenu and click the MegaMacro button (see screenshot).

If you are updating from an older version, delete MacroFrame.xml in your FrameXML folder.
