TextStyles Object (PowerPoint)
A collection of three text styles - title text, body text, and default text - each of which is represented by a TextStyle object.
Remarks
Each text style contains a TextFrame object that describes how text is placed within the text bounding box, a Ruler object that contains tab stops and outline indent formatting information, and a TextStyleLevels collection that contains outline text formatting information.
Example
Use TextStyles(index), where index is either ppBodyStyle, ppDefaultStyle, or ppTitleStyle, to return a single TextStyle object. This example sets the margins for the notes body area on all the notes pages in the active presentation.
With ActivePresentation.NotesMaster _
.TextStyles(ppBodyStyle).TextFrame
.MarginBottom = 50
.MarginLeft = 50
.MarginRight = 50
.MarginTop = 50
End With
