Does anyone know where I can find I big list of shortcut functions/coding syntax to help slim down the code making it smaller and/or neater?

For example:

IF test = X .or. test = Y .or. test = Z    could be  IF INLIST(test,X,Y,Z) 
or
IF LEN(ALLTRIM(test)) = 0  could be IF EMPTY(test)

There are always some we either don't know about, or haven't used in a long time and forget about...
