All of those single-key shortcuts also work as single-letter actions in the command buffer (below) and the hanging process stdin.

Single-Key Editing Shortcuts in the App (Default Layer)

Key	Action	Notes
q	Quit
0	Set zoom to 100%
c	(C)ommand	enter the command buffer layer
d	e(D)iting	enter the editing layer (if available)

Abbreviated Commands

Abbrv	Expansion	Arguments
pf	preview-frame	list of <frame-index> (space-delimited)
ps	preview-scale	<float>
ff	filter-functions	<regex>
rp	reset-filepath	<filepath>

These abbreviations can be typed into the command buffer in the app (available by hitting c), or into the stdin of the hanging process in the command line.

For example, once a coldtype program is running, you can hit c, then enter ps 2 to zoom the viewer to 200%-percent scale.
