[racket-dev] Feature request: documentation arrow in DrRacket

AFAICT the documentation arrow in DrRacket only appears if there is no
syntax error in the form (or before the form) you are clicking on.
This means I can't type something like for example:
#lang racket
...
...
(for*)
and then click on for* and see the documentation for for* and fill out
the rest of the syntax of the form.

It would be very useful to change this so that the documentation arrow
appears if you click on a form name even if you haven't filled in the
rest of the syntax for the form,

Thanks,
Harry Spier
