Un-SubD Key-stroke?

Probably been answered many times over but I can’t seem to figure out how to un-subD with a keystroke. I much prefer working in box mode in MODO and use the ‘Tab’ key to show smoothened, sub-divided results.

Is there a key-stroke in Rhino to un-smoothen?

Tab Key. [toggle smooth and box mode]


LOL…I should have tried before I posted. Thanks!
