I had a go at optimising the Sokoban 2a solution. I used a modified version of nhss to get a move list. I worked the previous version out at 755 keypresses, and my version at 585. I've put the move lists below here. You should be able to paste these into nhss using a copy of level 2a. You can't paste hundreds of keys into NetHack and expect nothing to go wrong.
