Sure, recorded here (sections 4/5, but the rest of the page should
also be better known; if only so that others would add their tips and
tricks as well; hmm, ghc-haskeline isn't there, yet):
Some of the items mentioned in the tutorial email have since been
added to GHCi, but I still use the :grep, :redir, and :ghc_pkg stuff;
:redir(Err) only works properly if -fbreak-on-exceptions is not
switched on, haven't investigated workarounds yet.
There is also a stub page for the GHCi debugger, nothing on it yet:
