[racket] Quick on-screen documentation

I believe this is interfering with Ctrl+n to launch a new window. It
doesn't interfere with Ctrl+t for a new tab.

Launch DrRacket, hit Ctrl+n, I get this:

add-panel: preferences dialog already open, cannot add new panels

I'd try to remove it to test if this script is causing the problem,
but I don't understand what I'm supposed to tell raco planet -e ???.

When I skip loading the tool, re-launch DrRacket, Ctrl+n, I get a
different error (so maybe it is not related?):

Any ideas?
