Seems like just adding to the Marker Name dialog box would be the way to do this....just have a "marker properties" section where an action/macro would be tied to that marker.
I'm guessing though, that someone already suggested this is the other thread
It might also be cool if markers with actions tied to them were a different color than standard markers. Hey...also what about a way to make the action/macro inactive? ...much like a plugin.
