Thanks everyone.
Yutaka, I typed in ENTER as you mentioned and it worked great. However, how can I get the ENTER text I typed in to NOT show up as text in the file?
The reason I want it to NOT show up is that I’m merging two files large files together (via the Tools>Split/Combine>Combine-Documents-into-a-single-file feature) and I don’t want the resulting file the have the ENTER text in it.
