Obviously the two tags should be made synonyms, I'm asking which one we should use. @Drew recently pointed to me, we had a question tagged as interactive-command, which is obviously a pleonasm.
I've changed that tag to commands, but I'm wondering if interactive-functions would be better. Or do we not need such a tag at all?
The tag should be commands. It could have interactive-function as a synonym, but I doubt that that will prove useful at all.
interactive is a Lisp special form. While some questions about commands (aka interactive functions) will also be about "function" interactive, and some questions about interactive will also be about commands, the two are not the same thing.
Another tag might be interactivity, which would deal with questions involving different ways to interact with users. (It would not be limited to dealing with commands.) But that is quite general, and it might be better to stick with tags for different kinds or topics of interactivity (mouse, menus, key-sequence,...).
interactive-function might be misinterpreted as referring just to the (interactive ...spec...) special thingy, so I think interactive-functions (note the final s) would be ever so slightly better.
I would be inclined to go with commands or interactive (To mirror function definition).
