This is still in the experimental stage. I didn’t do it on my real wiki.
I used TW-Commander to rename a few tags. Now I want to see which tags of mine are being used elsewhere that the tag text field. This is in case I may have to go and rename them where the old tag name may have been used.
I don’t know how to do this, that is search for my own tags (non system tags) that may be used in the wiki other than in their respective tag text field. If they’re not used elsewhere, then I don’t need to see them. Otherwise I would need a list of the relevant tiddlers for further inspection.
