@zenspider thank you for your comment, it would seem that clicking on identifiers don’t work for me, meaningthat the documentation display doesn’t change when I click on something. As far as I can tell, the only thing that works is what I just typed.

Ok I’ve discovered that the trick is you have to click on the lock icon or press F2 the keyboard equivalent to keep the popup open and only then clicking on identifiers will cause the popup to update

oh! yes, that is what I did too

sorry. I always have a doco browser open as I don’t use drRacket much

(just for debugging)
