Some buttons on Toolbar are greyed out

[Hobbled]

Some random buttons on my toolbar (MS-Word 2007) are greyed out--namely, the
highlighter button and the select justification buttons.

I have no trouble using these functions in the ribbon menu, just the toolbar
buttons.

Any ideas would be welcome.

Never mind.

I see, now, that the buttons I added to my toolbar (justification,
highlighter) were, in fact, buttons for use in some function called Word Art
(whatever that is) but when I eventually hunted down the correct buttons for
use in just regular text editing and put them on the toolbar, they work fine.

I assume that those greyed-out buttons would have been activated if I were
using Word Art.

Thanks for nothing!
