Returns or sets values specifying whether the selected text is automatically sub- or superscripted. When using automatic sub- and superscript the font is scaled and moved above or below the baseline with values defined through the font itself. Automatic sub- and superscript can be combined with a user-defined baseline which can be set with the [Baseline](https://docs.textcontrol.com/tx-text-control-activex/reference/txtextcontrol/baseline-property/llms-full.txt) property.

Introduced: 30.0.

### Syntax
