Key Combinations for 2D Math Notation
In parameter values, parameter names, and annotations, you can enter text in 2D math notation, which is a formatting option that allows you to add mathematical elements such as subscripts, superscripts, and Greek characters. This option also provides a symbol completion feature, which automatically suggests mathematical symbols to insert as you enter a phrase in 2D math notation.
To enter 2D math notation in a text annotation, select Math (
) in the text formatting toolbar.
To move the cursor out of a denominator, superscript, or subscript position:
•

Press the right arrow key.

The following table lists the key combinations for 2D math notation:
