Keyboard shortcuts (every binding, and how to change them) (part 2)

What it is

This is part 2 of the Keyboard shortcuts page. It covers the shortcuts you use while working in a session — starting, stopping and steering one, driving the message box — and the quick-response and AI bindings that sit beside them.

Where to find it

Same list, same place: Settings → Keyboard shortcuts, where every binding here can be rebound. This part is the reference copy.

How it behaves

Common shortcuts

These are the defaults — rebind any of them in Settings → Keyboard Shortcuts.

Sessions and composer

Shortcut	Action
N or Ctrl+T	Launch a new session in the current project. Exception: while the Quick Scratch Pad overlay (Ctrl+Shift+S) is open, Ctrl+T instead saves the current note and resets the editor to a blank fresh draft — the overlay stays open and the global new-session is suppressed
Ctrl+Space (global; ⌘⌥L on macOS)	Open the Quick Launch floating composer — type a prompt and submit to start a new session. Works even when Omniscio is in the background. macOS ships Cmd+Option+L by default (Cmd+Space is Spotlight)
Ctrl+Shift+Space (global)	Open Quick Launch on the KMS Find Note tab — fuzzy-jump to any KMS note by title. Works even when Omniscio is in the background; only registers when KMS is enabled. Rebindable as the "KMS quick find" System-wide hotkey
Alt+Space (global)	Open Quick Launch on the Task tab — jot down a to-do without leaving what you're doing. Works even when Omniscio is in the background. Rebindable as the Task tab's System-wide hotkey. (Windows uses Alt+Space for the window system-menu and PowerToys Run uses it too — whichever registers first wins.)
Alt+E (global)	Open Quick Launch on the Email tab — fire off a quick note to a saved recipient without leaving what you're doing. Works even when Omniscio is in the background; only registers when Quick Email is enabled. Rebindable as the Email tab's System-wide hotkey.
Ctrl+Alt+M (global)	Open Supermail in its own separate window (the pop-out) from anywhere — even when Omniscio is in the background. Only registers when Supermail is enabled. Rebindable as the "Supermail window" System-wide hotkey.
Ctrl+Shift+S (global)	Raise Omniscio and open the rich Quick scratchpad overlay (note list, pop-out, settings) from anywhere — even when Omniscio is in the background. This is the single scratchpad hotkey; the stripped-down floating-capture box that used to be on this key was removed.
Enter	Send the current draft (default Submit key)
Shift+Enter	Insert a newline instead of sending
Ctrl+Enter	Send (only if you set Submit key to "Ctrl+Enter" in Settings → Sessions)
Esc	Interrupt a running session with a safety double-tap — the first Esc shows a "Press Esc again to interrupt" hint, and a second Esc within ~1.5s actually stops it, so a single stray (or held) press can never kill a run. Esc clears anything else open first: it closes an open menu (only the menu — the session stays open), leaves a focused text box, closes an open file preview, then deselects a non-running session — interrupt is the last rung, so it never steals Esc from those
Ctrl+W or E	Archive the active session (closePanel action — labeled "Archive session"). When an inbox item is open instead of a session, the same key dismisses that item — an approval, or an in-pane detail pane (a held Sentry issue, a fired alarm, a PR / Jira / Linear / Granola / Notion / RSS / Telegram row) — the keyboard equivalent of that row's X / middle-click. And when the AutoHotKey editor is the open surface (the AHK project with a .ahk file selected, or no session yet), the same key closes the editor and returns you to the main inbox. And when a modal or slide-out panel is open — an open dialog (the search box, a confirm / editor / settings dialog, the command palette, an image preview, a setup wizard), the file / Markdown editor preview, or a side drawer (a meeting / integration detail) — Ctrl+W (like Esc) closes THAT instead of archiving the session behind it. In a popped-out session window (Pop Out) Ctrl+W is different again: it opens a close-confirm modal — Close window (keep the session running) / Close & stop session / Cancel — rather than archiving; see detached-session-window.md
P	Pause / unpause the active session — on an archived session, deposits it into paused (un-archive + pause atomically; bulk mixed selections handle archived + active arms in parallel)
H	Snooze the active session — opens the Snooze Palette; on an archived session, un-archives into ended first so the snooze flow can stamp snoozedUntil. When an inbox item is open instead of a session, the same key opens the Snooze Palette for that open row — an approval, or an in-pane detail (a held Sentry issue / fired alarm / PR / Jira / Linear / Granola / Notion / RSS / Telegram / SMS / drip) — the keyboard equivalent of right-click → "Snooze…"
C	Continue / Check in the active session — continues a stalled / ended / errored session, continues a session parked on a login-expired "re-authenticate" screen or on a usage-limit ("rate limit") screen, or checks in on a session waiting on its 30-min auto-wait timeout (whichever banner is showing). Mirrors the composer Continue / Check in button exactly; sends nothing when neither banner is showing. Like every single-key shortcut it fires only when the message box is not focused — so a paused / stalled / errored / ended (or re-authenticate- / rate-limit-parked) session lands your cursor on the conversation and C continues on entry; click the box (or press R) to type, after which C types a literal c
W	Keep waiting — re-arm a silent wait on a session that hit its auto-wait timeout (the "Keep waiting N min" button; N is the keepWaitingMinutes setting, default 60), without messaging the agent; no-op otherwise. Like C, it fires only when the message box is not focused; inside the box it types a literal w
Y or Enter	Allow the tool-permission request showing above the composer ("Claude wants to run…" / "…access a sensitive file"). Mirrors the card's Allow button exactly, and both keys run the same handler behind the same single in-flight latch, so a keypress racing a click can never answer twice. Silent no-op when no card is showing. Enter stands down whenever a button or link already has focus — so Tab-ing to Deny and pressing Enter denies — and inside the message box Enter still sends your message. One caveat to this table's "rebind any of them": Y is rebindable, Enter is not — it is fixed and never appears in Settings → Keyboard Shortcuts, because a rebindable Enter would swallow Enter app-wide on every focused button and link. It is listed instead in the keyboard overlay (the ? shortcut list) under Session
X	Deny that same request — mirrors the card's Deny button; silent no-op when no card is showing. Inside the message box it types a literal x
T	Tag the active session — opens the Tag picker palette
R	Focus the composer textarea so you can type a reply
Q	Focus the Question Widget (if one is showing)
Ctrl+E	Toggle the File Explorer panel for the active session — silent no-op when no session is selected (Inbox / Settings views)
V	Toggle Plain Speak ⇄ Original on the latest agent message that has a Plain Speak rewrite — silent no-op when no eligible message exists; doesn't fire while typing in the composer (or any input / textarea / contenteditable)
Ctrl+Shift+Q	Open the first link in the agent's most recent reply, in the active reading pane (drip / alert / digest / weekly summary / scheduled message), on the task row you're focused on in Tasks, or the first web link in the Supermail email you're reading — same routing as a real click. Hovering that first link reveals this shortcut as a tooltip (except inside a Supermail email, whose body renders in a sandboxed frame)
Ctrl+Z	Undo your last session action (archive, pause, snooze, move, rename, close). Reverses it even with the cursor in any text field that holds a draft — until you start typing, after which Ctrl+Z undoes your text instead (never your draft). Press repeatedly to walk back through recent actions. (Bare Z is no longer bound — it used to undo from outside a text box, but a stray "z" could revert silently; rebind it in Settings → Keyboard Shortcuts if you want it back.)
Ctrl+Y	Redo your typing — puts back text you just removed with Ctrl+Z, in the message box or any text field (Ctrl+Shift+Z does the same).

Quick-response and AI

Shortcut	Action
Alt+1 / Alt+2 / Alt+3	Send the 1st / 2nd / 3rd AI suggestion
Alt+S	Open the snippet (quick reply) picker
1–9 (picker open)	Fire the quick reply showing that number badge — honors its auto-submit setting. Positional by default; pin a fixed number per reply in its editor. Fires only when the picker's search box is empty. Toggle: Settings → Quick Replies → Number-key quick send
Alt+Z	Send the configured Zap quick-reply text — rebind via Settings → Keyboard Shortcuts → Session → "Send quick reply" (the duplicate per-snippet input previously under Settings → Snippets was consolidated into the main Keyboard Shortcuts panel)
Ctrl+U	Open the file attachment picker
Ctrl+Shift+L	Send Later — schedule the current draft for future delivery (a session composer key; the Quick Launch → Task tab uses the SAME chord for its Send Later picker, which files the task snoozed — consistent, and conflict-free since the Task tab is its own window)
Ctrl+Shift+P	Open the Command Palette (Quick Launch) — one searchable box to find and run any main app action; with the universal command palette enabled it also reaches every navigation hub and setting
Ctrl+Shift+K	Open the Super Prompts picker (moved here from Ctrl+Shift+P when the Command Palette took that chord — rebind either under Settings → Keyboard Shortcuts)
Alt+V	Start a voice command (push-to-talk)
