^^ Of course you don't: just tell Arc about what you do remember, and it'll tell you more about related things you might want to look at too:

  arc> (help map)
  (from "arc.arc")
  [fn]  (map f . seqs)
   Applies the elements of the sequences to the given function.
      Returns a sequence containing the results of the function.
      See also [[each]] [[mapeach]] [[map1]] [[mappend]] [[andmap]]
      [[ormap]] [[reduce]]

I know, but when was the last time you thought you needed help with map of all things? :)

Actually, aha! I added this to the bottom of ~/.arcshrc

  (let func (random-elt:keys help*)
    (prn "Documentation for " func " " (helpstr func)))

Now whenever I start arc, it will print, e.g.,

  Documentation for saferead (from "arc.arc")
  [fn]  (saferead arg)
   Reads an expression, blocking any errors. 
  
  Use (quit) to quit, (tl) to return here after an interrupt.
  arc>

And thus hopefully I will learn something :)
