editing/viewing all keywords in the database

[timoteo]

Using imatch 2025.3.2 on Windows 11.

I want to see all keywords used in my database for all pictures but I can't find how to do this. I remember finally figuring it out in my old version but it was less than obvious to me. I don't understand why there isn't just a "keywords" with "Media & Folders", "Categories", "Timeline", etc. With my old version of imatch, I remember I had to do somehing which was not obvious. If I recall correctly, I selected my top-level directory ("Database") from the list of folders, then clicked on "Open Thesaurus". I've gotten that far and have my thesaurus manager open and can see all my keywords.

What I want to do is delete logical duplicates. e.g., show all images that have the keyword "churches" assigned, then assign "church" to all of them and delete the keyword "churches" from the keywords entirely. I have used both keywords over the years and want to merge them all into "church".

I can select the "churches" keyword but I cannot show (so far) all images assigned "churches" nor see how many images are assigned "churches". 

I'm confused. It's late and I'm tired, but this seems to be far more difficult than I imagined, or I am "barking up the wrong tree" here?

Please help.
