Iderdnev, I hope someone knows of a utility or Python script that can do what you want, if not then perhaps the ideas below will at least be better than compiling the list by hand. In Poser 4 select an actor (body part), then from the Edit menu select copy. Paste the clipbord contents into a text editor. The result will be a listing of all the none-hidden channels in that actor. Normally the morphs will be listed first, then the Taper channel, then the scale and rotate channels. Here is what you get if you copy and paste from Posette,s chest:

Chest   0       Small   Spline  0.0000
Chest   0       Large   Spline  0.0000
Chest   0       Droop   Spline  0.0000
Chest   0       Hi-nipple       Spline  0.0000
Chest   0       Cleavage        Spline  0.0000
Chest   0       heroine Spline  0.0000
Chest   0       taper   Spline  0.0000
Chest   0       scale   Spline  1.0000
Chest   0       xScale  Spline  1.0000
Chest   0       yScale  Spline  1.0000
Chest   0       zScale  Spline  1.0000
Chest   0       yrot    Spline  0.0000
Chest   0       zrot    Spline  0.0000
Chest   0       xrot    Spline  0.0000

Obviously you can edit this to leave a list of morph targets, but you would have to repete the procedure for each actor. An alternative to the above may be to use the free utility Mat Pose Edit to make a pose file containing only morph targets, zero those morph targets. Then you should be able to open the resulting pz2 in a text editor, and use its search and replace function to delete much of unneeded stuff in the pz2, and with a bit more editing by hand you will be left with a list of morpf targets.
