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

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_

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?
