I forfeited some of my weekend to use a simple project at work, that I could do
in an hour with Python/JS, to cut my teeth on #racket-lang
Serendipitously, I discovered the C-M-p and C-M-n shortcuts while trying to
navigate the geiser repl. I see that the commands are called 'backward-list'
and 'forward-list', respectively. They jump to parentheses ends and beginnings.
These names are the reason I can never find the obvious things in #emacs
