overset text when there's tonz of space

In addition to Manan's and Willi's suggestions, long URLs can cause a story to become overset.

1. Keep options
2. Foot notes
3. Using input key (from number pad) instead of return

Could be many things, can't guess without looking at the content. One use case I can think of is of a word which is too wide to be accomodated in the textframe. This could be due to say some nobreak setting applied. This is a case where the overset is non resolvable and it will be overset even if there is lots of space in the frame
