Ah yes, that seems like a useful reference in the manual, and I always prefer to read documentation and learn on my own instead of asking on forms. I actually did a search in the manual for “context menu” before asking here, but it didn’t seem to find anything related at first glance. Now I realize that it only finds the titles of sections that may mention the keword, without highlighting any results.
So the search in the documentation isn’t great, especially for new users who don’t understand how it works and may think that it’s not finding their topic.
And what you said about the command location which has to be contained within a certain code structure, also makes perfect sense.
Thanks again.
