I knew about the binding and the lock/unlock button, which are pretty
convenient. It does still mean you have to move the mouse & click, and
then press f2 to get the information though (as opposed to just hover
over the binding and it pops up automatically).

Also, I think the current behavior could be confusing in some cases.
Here's an imaginary workflow (_ is insertion point):

  (require_ racket/function
            racket/list)

Press f2, get a box showing the info for `require`. That's good. Press
f2 again to hide it. But then you move the insertion point:

  (require racket/function_
           racket/list)

Press f2 again. I might be expecting DrRacket to show me information
about the `racket/function` module, but instead it shows me the grammar
of require. Maybe it should show nothing if the insertion point is not
currently on an identifier it can show meaningful info about?

Cheers,
