Inverse Word Wrap tool?
Are you saying you want the text to follow the path of the circle? You wouldn't need to do anything special to fill a a circle with normal lines of text... Not sure if you mean a regular text wrap outside the circle, or text following the path on the outside, either.
You can set a text frame to either ignore or honor text wrap, but it's all or nothing using the checkbox in the frame options. If you go into the prefs and set wrap to only affect objects below you might get waht you want by adjusting the stacking order, but I sitll don't have a clue waht you are trying to do.
Screen shots might help.
Jongware, you hit the nail on the head! that is the exact look I'm going for.
Peter, I'm sorry if my description was unclear, this was a difficult issue to explain. My apologies for using the wrong terminology, by "inverse word wrap tool," I meant using the text wrap tool and checking the box for inverse.
In any case, the image that Jongware provided is the desired look I'd like to achieve. I'll play around with this and Jongware, if I have any further questions, I'll post back here and direct to you.
