It should be noted that simply pausing a fight and clicking 'Move List' does NOT work (it didn't for me at least.)
There are a few different ways to do this, but since I think a lot of people go into the training mode first to re-learn how the game works, my suggestion is go into training, pause, and click 'Begin Command Training'. This will display move combos on the screen while fighting, and will also pop the achievement.
