debug-on-error while starting up
no cursor in non-selected windows
alias override he-dabbrev-beg

this simplification was mainly inspired by trying to get ruby symbol names to
expand when their non-symbol versions existed in buffers
trying out `toggle-quotes`
use `dired-toggle` instead of `dired-jump-other-window`
use bind* use-package key, some random cleanup
added `swoop`
