[IPython-user] ipython.el + pdb rocks!!!

[cc-ed to the list, in case someone else wants to try this out and have the
same epiphany I've had today]
I can't thank you enough for ipython.el and the pdb integration. I know I
should have tried this long ago, you'd said as much.
Today I've been wrestling a really hard structural bug in a fairly complex
code, and I was going crazy tracking down the call chain, even with manual
%pdb usage in ipython. There were just too jumps I needed to understand, and
the 'l' command in pdb, while useful, is sometimes just not enough.
I remembered you had mentioned, several times, how your setup involved %pdb
but within ipython.el. I tracked (via an old response of yours on the list)
how to activate pylab with C-c !, and reran my nasty code with %pdb on. In
about 30 minutes I've been able to tame this beast, which I knew was going to
be a major nightmare with the regular tools. This setup absolutely ROCKS, the
automatic source jumping with u/d, along with the (still active) ability for
variable examination, are a dream: you can fly through the source and memory
state of an entire program in a really incredible way.
Anyway, this is just a bit of fan mail :)
ps. Now that I've suckered up to you, let me ask a question: the one thing
that's annoying me is keyboard management. In a terminal, ctrl p/n do
previous/next _only_ in the history that matches the current line. Is it
possible to rebind the keys in Xemacs so that, in an ipython buffer, you get
also ctrl p/n to do history matching (like ctrl up/down do?). I'm OK with
losing ctrl p/n for moving the text caret, the arrow keys still do that. It's
just that my muscle memory is tripping me badly, when I switch from ipython
in a terminal to ipython in an emacs buffer.
