Adjusting Spacing Within Text Box Borders
The space between the borders of a text box or shape and the text within it is called
the inset margin. You can adjust this spacing using a slider in the Text inspector.
To adjust the inset margin:
Select a text box or shape containing text.
Click Inspector in the toolbar, and then click the Text inspector button.
In the Text inspector, click Text.
Drag the inset slider at the bottom of the Text inspector to achieve the look you want,
or specify a value in the adjacent field.
Specify how much space you
want around text inside a text
box, shape, or table cell.
