I am a bit puzzled - maybe I'm doing something wrong.

When I create a new text box by clicking on the Text icon on the Drawing toolbar, I cannot use the Promote/Demote buttons in the Text Formatting
toolbar (they are grayed out) to change the outline level of the text. However, using the Tab key and Shift+Tab keys to promote and demote the outline level works fine!
If I instead use text boxes created from the Layout pane, also the buttons work perfectly.
OK, I admit it's not a serious thing.
