Version: 7.1.5.2 / LibreOffice Community Build ID: 85f04e9f809797b8199d13c421bd8a2b025d52b5 CPU threads: 2; OS: Linux 5.4; UI render: default; VCL: gtk3 Locale: en-GB (en_GB.UTF-8); UI: en-GB Calc: threaded 1. Go to the LO Writer "Edit Index Entry" help file: https://help.libreoffice.org/latest/en-GB/text/swriter/01/02160000.html?&DbPAR=WRITER&System=UNIX 2. Look at the entries for "End arrow to left" and "End arrow to Right". The explanations do not accord with the observed behaviour in Writer, and, AFAICS, are wrong. ACTUAL BEHAVIOUR In the program, clicking the "End arrow to left" selects the PREVIOUS index "Entry" of the same name – NOT the first entry. Similarly, clicking the "End arrow to right" selects the NEXT index "Entry" of the same name – NOT the last entry.
I can confirm the reported behavior. Buttons "End arrow to left" and "End arrow to right" only appear when there are two or more entries with the same name. Using these buttons navigate through all entries with the same name (left = previous; right = next). I think we also need to add tooltips to these buttons in the dialog as well, to make it clearer to the user what will happen when they're clicked.
Created attachment 177328 [details] Sample file with index entries Here's a sample file showing the problem. It contains some Index entries, among which the entry LibreOffice is repeated 4 times. If you right click any of the "LibreOffice" entries and choose Index Entry, the arrows to navigate entries with the same name will appear in the "Edit Index Entry" dialog. Note that they work as previous/next buttons instead of first/last, iterating over all entries with the same name. The other arrows work as previous/next, however considering all entries.
