Double-click in/on or manually highlight ANY operator or built-in function  
and press the Help key.

For instance, double-click on /, @, or between them in /@, push Help, and  
you'll see Map.

Doing the same for % gives Mod (ignore that; it should NOT come up!!) and  
Out.

Out is the one you want. To oversimplify... % means the previous result.
