I have a lengthy index. Most of it is fine. A couple sections are repeating the main entry above each sub-entry. To trouble shoot the problem, I created an simple index entry in a different color, basic body text style, and pasted it on four different pages.
Four page numbers should have come up (in red) for the main and identical subheadings. Instead, I have four separate entries.
I am posting my problem under Dydoria's question because I hoped by pursuing how to do it, I could undo it.
What I discovered is the problematic index sections are listing by page number rather than alphabetically. There is no code in the entry to define that. If there could be a hidden code or keystroke somewhere else in the document, I need to know what it is so
I can look for it and eliminate it.
By the way, these sections worked once, then went haywire as described above.
