Controls for atari 2600 in MESSUI

I got the controls to work for in MESSUI 0.134 for Atari 2600 but I think I'm missing what some controls are like system reset and all that. I know the arrow keys to move and the Q is fire. "2" also gets some games playin and F3 is soft reset. Tried going into the settings but couldnt find anything for the 2600. Mainly the controls for the dials on the system are what I need. Thanks

Go into the TAB menu in-game and select 'controls for this system' you can define them all in there.

thanks for the info. I did that but didnt see everything. Plus a few games like breakout and some kids games wouldnt let me move. manual for kids games said use kids atari controller.
