MAP - have not seen this before and it is redundant MOR is the keys for morph channels (dial settings) POS pose would be position = rotations usually, but a Poser generated POS .pz2 has both rot keys and trans keys, so a pose file that does trans is a POS pose. (Position) MI pose would be morph injection (It has been called delta injection and MORdonor, but V3 kinda sets the injection term, even if it is not really either and injection or a donation - it is a replacement - because the channel has to be in the target cr2 for it to work and it just changes the deltas in an existing morph channel. There is no way to insert an entirely new morph channel using a pose file.) JNT pose would be for JP changes, scaling, ERC, setting limits for channels, hiding channels - the housekeeping catch all. A pose that does MAT (everything in a materials block) and MOR should probably just be called a character pose rather than try to make an abbreviation for it.
