I don't see any way to adjust the padding for the Textbox and Callout . . . I'm talking about the distance from the line, or box around the text, to the text. I would like there to be a small distance.

If I highlight the text within the box:

I can then set Line Spacing to . . . 3.00 . . . this isn't bad for vertical

But with Character Spacing, keep it at . . . 0.00 . . . this doesn't help for horizontal padding
