Changing the font on NavBar buttons

You can change the font used for the button labels on a NavBar easily. Select the bar by clicking on it. Then go into the Text Tool and select from the font list on the left of the Text Tool InfoBar. As you move the mouse pointer over the different fonts in the list, the NavBar updates immediately so you can see how that font would look. Select the required font. If your bar has a mouseover state, it is also updated to use the same font.

Similarly you can change the size of the font using the font size control which is next to the font selection list.
