Expression Function Reference

The tokens in this reference can be inserted into expressions using the Function button or the Edit Insert Function command of the expression editor. You can combine and nest these tokens to create complex expressions using brackets ( and ) as well as Operators and numeric values you type.

For more information about expressions in general, see Animating with Expressions [Animation].
