Zen settings

The zen key holds the settings of zen mode. Change them with Z or by hand; missing or invalid fields fall back to the defaults. Zen itself always starts off.

flow	"scroll" or "pages"	"scroll"
spotlight	boolean	true
typewriter	boolean	true
ghost	boolean	true
prompter	boolean	false
wpm	120–400	220
measure	60–100, or "full" for the whole pane minus a 2-column margin (> past 100 reaches it)	72
