Hi. I have a mild preference to C-up/down, but M-n/p is just fine also.
As for the coding style, I've looked through that file
(notmuch-hello.el), and it doesn't seem to have a consistent style as
far as tabs/spaces go. I'm happy to change my patch to conform, but I
don't know what I should be conforming to. Should I be tab-ing all
indents, or just some?
