Key Bindings

Keys are contextual: the same letter means different things in the diff, in the comments panel and in the PR overview. Each table below is one surface.

g? opens the keymap overlay — this page, condensed, without leaving the app. Ctrl+p opens the action menu, which is the authoritative list: it shows only what applies to the state you’re in, with the shortcut next to it. Bindings are not configurable yet.

Motions

In the diff. These follow vim, including the ones you only notice when they’re missing.

Key	Action
j k	Down, up (arrow keys too)
h l	Left, right
w e b	Word forward, end of word, word back
0 ^ $	Line start, first non-blank, line end
f{char} t{char}	Find character forward, till character
; ,	Repeat that find, forward and back
Ctrl+d Ctrl+u	Half page down, up
gg G	Top, bottom of the diff
V	Visual line mode — select a range for a comment or a yank
Esc	Leave visual mode, or clear search highlights

Long lines

The diff scrolls sideways rather than wrapping, and moving the cursor carries the view with it. These are for moving the view on its own.

Key	Action
zl zh	Scroll one column right, left
zL zH	Scroll half a screen right, left
zs ze	Put the cursor’s column at the left, right edge
gl	Peek the line in full — or, in a markdown table, the table as a grid
zw	Toggle soft wrap for the whole diff

Jumping

Key	Action
]c [c	Next, previous hunk
]f [f	Next, previous file
]u [u	Next, previous unviewed file
]o [o	Next, previous outdated file — viewed, but changed since
]r [r	Next, previous comment thread
]n [n	Next, previous comment you have not seen
]R [R	Same, skipping resolved threads
]g [g	Next, previous commit’s diff; wraps back to the full diff
s	Flash jump — search what’s on screen, press a label to land (file headers included)
Ctrl+o Ctrl+i	Jumplist back, forward (Tab is forward too)

Every one of these records a jumplist entry, so Ctrl+o undoes it.

Search

Key	Action
/ ?	Search forward, backward
n N	Next, previous match
* #	Search the word under the cursor, forward and backward
Esc	Clear the highlights

Folds

Key	Action
za	Toggle the fold at the cursor — file header, hunk, or fenced code block
zA	Fold or unfold every fenced code block in this file
zo zc	Open, close it
zR zr	Open every fold
zM zm	Close every fold
Enter	On a context divider: reveal the hidden unchanged lines

Expanded context lines are for reading only — GitHub can’t anchor a comment outside a hunk.

Files and panels

Key	Action
Ctrl+b	Toggle the file tree
Ctrl+e	Toggle the file tree — or the comments panel, when it has focus — to full width
Ctrl+h	Move focus left: comments → diff → tree
Ctrl+l	Move focus right: tree → diff → comments
Ctrl+t	Toggle the comments panel
Ctrl+f	Fuzzy file picker, from every view
/	Filter the list that has focus — tree, PR overview, feed, comments panel; search, in the diff
Ctrl+g	Pick commits to scope the diff to — Space marks, V marks a run (Esc in the diff leaves it)
v	Mark the file viewed and advance to the next unviewed
Esc	Leave single-file view — after clearing a selection or search highlights

In the file tree: j/k moves, l/Enter opens a file or expands a folder, h collapses, v toggles viewed, / filters by path, Esc hands focus back to the diff.

Filtering: / opens an input in the panel header, typing narrows the tree live (loosely, against the whole path — apicl finds src/api/client.ts), Enter keeps the filter and returns to navigating it, Esc drops it. It’s a real text field, so Ctrl+w, word jumps, paste and undo all work.

Backspace (the same key as Ctrl+h) walks focus left first, so coming back to the tree keeps the filter; once there is nowhere left to move it clears an applied filter. Esc in the tree clears it too, after any multi-select and before leaving the panel.

Comments

From the diff:

Key	Action
c	Comment on the cursor’s line, or on the visual-line selection
C	The same, drafted in $EDITOR
E	Edit the thread on this line in $EDITOR
Enter	Open the thread on this line in the comments panel
gC	Fuzzy picker over every comment in the PR

In the comments panel (focused — Ctrl+t, or Enter on a thread):

Key	Action
j k	Move between comments
J K	Jump to the next, previous thread
Ctrl+d Ctrl+u	Half a screen of comments
za / Enter	Expand or collapse the highlighted thread
n	New thread at the diff cursor’s line
s	Flash — label every visible comment, next key jumps
g?	The keymap
gx gX	Pick from every link in the panel’s comments — open it, or copy it
r R	Reply inline, reply in $EDITOR
e E	Edit inline, edit in $EDITOR
d	Delete the highlighted comment
x	Toggle the thread resolved
S	Post this one comment now
y	Copy a link to it
o	Open its file at its line in $EDITOR
q Esc Ctrl+h	Close the panel, or hand focus back

While writing a comment:

Key	Action
Enter / Ctrl+s	Save locally
Ctrl+p	Save and post it to GitHub now
Ctrl+j	Newline
Ctrl+g	Continue in $EDITOR
Ctrl+y	Insert a suggestion block for the lines the comment replaces
@	Mention picker — ↑/↓ or Ctrl+p/Ctrl+n, Tab/Enter accepts
:	Emoji picker, same keys — :roc → 🚀
Esc	Cancel

Ctrl+Enter also posts, in the terminals that can send it. Ctrl+p is the one that works everywhere, tmux included. In local mode both just save — there’s nothing to post to.

GitHub

Key	Action
gS	Submit review — opens the preview
gs	Sync edits, replies and resolutions
gr	Refresh diff, commits and comments
gi	PR overview panel
i / a / d	PR state / feed / diff — the same key again goes back
c m r b t p u	In the feed: toggle a type, unseen only; Esc puts everything back
za	In the feed: open a commit into its files
go	Open the PR in a browser
gy	Copy the PR URL
gY	Copy a permalink to the selection, line, or file
gP	Edit the PR title and body — or create a PR, in local mode
gc	Check out the PR branch and open the file in $EDITOR

In the review preview (gS): 1 2 3 pick comment / approve / request changes, Tab switches between the summary box and the comment list, j/k walks it, space excludes a comment from this review, Enter or Ctrl+s submits, Esc backs out. The sync preview (gs) is simpler: Enter confirms, Esc cancels.

PR overview

i or gi gets you here. Sections are description, conversation, checks, approvals, commits and files.

Key	Action
j k	Move
l h	Expand, collapse the selected item
za	Fold the section, thread, or check under the cursor
zr zR / zm zM	Expand, collapse one section or all of them
c	Write a conversation comment
x	Toggle the focused review thread resolved
Enter	Context-dependent: open a check’s annotation in $EDITOR, expand a failing check, or open the item in a browser
y	Copy a link to the focused item
gg	Top
g?	The keymap
gx gX	Pick from every link in the overview — open it, or copy it
gr go gy	Refresh, open in browser, copy PR URL — as everywhere
s	Flash — label every row, next key jumps
q Esc Tab i	Back to the diff

Editor and clipboard

Key	Action
gx gX	Follow the link under the cursor in the browser, or copy it
gf	Open the current file in $EDITOR at the cursor’s line
gF	The same, in a new tmux window, with riff still running
y	Yank the line or selection, without the +/- gutter
Y	Yank it with the gutter intact
gd gD	Diff this file’s two versions in $EDITOR, in a tmux pane

Pickers and menus

Every fuzzy picker — files, comments (gC), commits, the action menu (Ctrl+p) — takes the same keys: type to filter, ↑/↓ or Ctrl+p/Ctrl+n to move, Enter to choose, Esc to cancel. They all type into the same input widget, so Ctrl+w deletes a word, Ctrl+u the line, and word motions, paste, undo and selection work in every one of them — the filter prompts included.

Global

Key	Action
Ctrl+p	Action menu
g?	Keymap overlay (Esc or q closes)
Ctrl+o	Jump back
q	Quit
y / n	Answer a confirmation dialog

Chords (g, z, ], [) time out after half a second, so a g you didn’t mean to press costs nothing.
