I am prompted to ask by Name in English of different parts and tools.
Maybe it's obvious, but each time I've wanted it I had to dig around. (Yes, it's a favorite now :-)
I see a link on What topics can I ask about here?, but can it be in an easier-find-place?
Update:
After some more experimentation I think the "Questions that may already have your answer" feature just does a word match between the [question] title you type and other titles and content, with titles more highly weighted. Maybe it uses tags also, but I haven't experimented with that.
Another update:
I have added an answer that proposes changing the terminology index page. Your votes on that answer will be used to decide whether to proceed.
