How do I rotate backward instead of forward?

I have the bases down and know how to rotate, but I struggle to figure out how to rotate backward instead of forward. The rotate seems to be set up only in a clockwise motion. Do you know how to move it counter-clockwise? It would be helpful one animating characters, overlays and such. Thank you so much! :blush:

Put a negative in front of the number

@overlay OL rotates -90

Really?! Thank you so much! :grin:
