I use `!rust` all the time when I just want to pull up the rust docs quickly, since their search is much more effective when I just want to know about the API for a File or something, though I don't get much more value out of them than that. And I've just learned I can use `!posix` to search the open group, which I'll probably use whenever I get upset with macOS's man pages again.
