Awesome - thanks. I'm not sure if you meant 'insertion point is on the word "filter" ', or not, but for fun, I hit F1 with the insertion point on "help" and got meta-help which showed me 18.3 Interactive Help. I then evaluated (require racket/help) in the repl, then tried evaluating (help filter) A web page was opened, but not the help for filter (it was 4.9 Pairs and Lists), and the repl had the following: > (require racket/help) > (help filter) Loading help index... Sending to web browser... file: /Applications/Racket v6.3/doc/reference/pairs.html anchor: (def._((lib._racket/private/list..rkt)._filter)) osascript: OpenScripting.framework - scripting addition "/Library/ScriptingAdditions/Adobe Unit Types.osax" cannot be used with the current OS because it has no OSAXHandlers entry in its Info.plist. > Hitting F1 when the insertion point is on filter works great though :) I also tried (help "filter") and that does open up a more relevant page - the search results for searching help with filter; where the command-line repl opens up the page with the help for filter - the command-line (help) form appears to expect a procedure symbol and shows the specific help for it. > On Tue, Jan 26, 2016 at 4:28 PM, Brian Adkins wrote: > > I was doing some reading on Scheme, and I came across the following page: > > > > http://bastibe.de/2012-09-20-story-about-schemes.html > > > > The author mentions: > > > > "That said, I found plt-racket to be a joy to work with.
