Key Bindings

presto is vim-flavoured: j k move, g ⇧G jump, lowercase acts on the selected PR, and ^P lists everything else. Every binding here can be changed in [keys].

Press ? at any time for this list in the app; esc, ? or q closes it.

Navigation

Keys	Action
j / k (or ↓ / ↑)	move down / up
g / ⇧G	top / bottom
^D / ^U	scroll the preview half a page down / up
p	toggle the preview panel
⇧P	move the preview: right → bottom → off
c	expand / collapse the gate columns (C R B) behind the merge verdict

Open

Keys	Action
↵	open in riff; presto refreshes when you come back
⇧O	open in riff in a new tmux window, presto keeps running
o	open in the browser
⇧D	pipe the diff through your diff viewer (delta, bat, or less)
x	open the failing check — one red check opens its job page, several open the checks tab, none opens the branch’s workflow runs
space	gh pr checkout in the local clone

Copy

Keys	Action
y	copy #number
⇧Y	copy the URL
b	copy the head branch name

Filter

Keys	Action
/	open the filter prompt; tab autocompletes, ↵ applies, esc cancels
⌫	clear the filter (when one is active)
^E	toggle @me
^U	toggle >unread (when the preview is closed)
^M	toggle >marked
^R	toggle >recent
^S	toggle >starred

Marks, stars, unread

Keys	Action
m then a–z	mark the PR with a letter (again to unmark)
' then a–z	filter to that letter; '' clears
s	star / unstar the author
v	toggle read / unread

Tabs

Keys	Action
t	new tab (a copy of the current one — change its filter)
d	close the tab
u	undo the last close
[ / ]	previous / next tab
1–9	switch to tab N

Everything else

Keys	Action
^P	the command palette — every action, filter and column toggle, with a search box
r / ⇧R	refresh
?	this list
`	toggle the console (request log)
q	quit

In the palette

^N / ^P (or ↓ / ↑) move, ↵ runs, esc closes. Dangerous commands — close, re-run checks — ask for a second ↵. Dialogs (merge, review, workflow) have their own hints in the footer: number keys pick an option, ^J inserts a newline in a review body.
