It does still mean you have to move the mouse & click,
I almost never move the mouse and click to move the insertion point. I can see, however, that if you're already moving the mouse a lot then being based on the insertion point is a wash. > 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`.

The flip side of this coin is when you have this: (make-output-port_ a b c d) and you want to go edit the arguments while the blue box is on the screen (this happened to me yesterday (with a different function but I forget now which one)). It is this kind of use of the blue boxes that, imo, will make mouse-movement based boxes too fragile. You'll have to leave your mouse on top of make-output-port, which can leave lots of other stuff on the screen (due to check syntax).
