All is not in the title as, like in every application, there is a conventional glossary were words like “contents” or “list” have a specific definition which is not the same as every lay man. Similarly, you have a goal but you didn’t clearly describe it nor your context (structure of existing document).
You are encouraged to edit your question to improve it and mention both OS name, LO version and save format (.doc(x) or .odt). Note that most recipes will work only for native .odt format.
The quickest solution, not involving manual markup of your document, is to use a concordance file. The procedure is as follows:
- where tou want your alphabetical index,
Insert
>TOC & Index
,>TOC, Index or Bibliography
- in the
Type
tab, select Alphabetic Index
from the Type: drop-down menu
- tick Concordance File
- select
New
from the drop-down menu
Enter a few words to begin to populate your file. It is tedious to enter 880 keywords manually. If you have your list already in a file, save the concordance file and quit LO.
Open the concordance file (extension .sdi) in any text editor, not Writer (or else be wise enough to save as plain text, but the process is error-prone). Have a look at how the keywords are encoded, one per line.
Then either merge your list into the .sdi file, or add the flags to your list. The flags and attributes are separated by semicolons.
When your concordance file is ready, reopen your document with Writer and refresh the alphabetical index.
