From	To
control + i / j / k / l	Arrow keys
control + u / o	home / end
control + e / s / d / f	shift + arrow keys
control + w / r	shift + home / end
control + n / m	page up / page down
control + delete (backspace)	option + delete (backspace) (delete a word)

This works better when caps lock and control are switched.
