Combat Tracker abbreviations

[Jundle]

What are all the different abbreviations in the combat tracker, and what do they represent? I've seen [EFF][M] and [mi]. I assume [EFF] means effect, but what do [mi] and [M] mean?

I was hoping someone more knowledgeable might weigh in on this, but based on my own observations, [mi] seems to indicate the power is a minor action, and [M] that it is a melee attack. Other examples include [mo] (move action) [C] (close) [R] (ranged), [e] (encounter power) and so on. I assume that standard action is the default action, and At-Will is the default usage, so there is no special notations for powers with those properties.

My advice is to check each power back on the original creature's NPC entry and try to make connections based on what you see there. There's usually very little text to sift through so something relevant should pop up pretty quickly.
