Keyboard Shortcuts

Shortcuts are written here with macOS modifiers. Substitute as follows and everything on this page works on Windows and Linux too:

The new-thread chord ⇧⌘O is Ctrl+Shift+O, and the tab-stepping chords ⌥⌘← / ⌥⌘→ are Ctrl+Alt+Left / Ctrl+Alt+Right. Function keys are the same key everywhere.

The one exception: ⌃

⌃ is a separate key only on macOS. Everywhere else it is the same physical key ⌘ already stands in for, so a chord that needs both can never fire there. Three chords are macOS-only for that reason, and Qubis hides their chips on the other platforms rather than advertising a shortcut that does nothing:

Find and replace is the other chord that is not a straight substitution — it is ⌥⌘F on macOS, Ctrl+H on Windows and Linux. macOS claims ⌘H for Hide Qubis before the window sees the key, so replace takes the Mac convention instead.

A few keys check the physical Ctrl key instead, and so behave identically on every platform: ⌃C to interrupt the agent (a pending question goes with it), ⌃Space for completion, and ⌃ + left-drag to orbit the viewport.

Inside the palette, the All / Agents / Commands / Files / Plugins / Skills pills are cycled with Tab and ⇧Tab, or with the bracket keys ⌘[ / ⌘]. A shortcut a visible row prints runs that row while the palette is open. The editing chords are the exception: undo, redo, select all, copy, cut, and paste belong to the query field while you are typing in it.

Agent

Queueing and steering

While the agent is working, Enter queues your message behind the current turn, and the queue sends in order once the turn ends.

⌘Enter (Ctrl+Enter on Windows and Linux) steers instead: the message goes to the agent now, without stopping it, and the agent picks it up after its current step. On an idle thread the two keys do the same thing.

Messages already in the queue can be rewritten or reordered too. With the composer empty, ↑ pulls the queued prompts back into the composer as one block, joined with a blank line between them, so you can edit the batch and press Enter to queue it again as a single message. A message that carries an attachment, or that replaces an earlier one, stays in the dock instead: steer or remove those on their own.

To take back one message, ↓ selects the most recent queued message,

↑ / ↓ step through the rest, Enter pulls the selected one into the composer, and ⌘Enter steers it into the running turn ahead of the others. With nothing selected, ⌘Enter steers the newest queued message without touching the composer.

Each queued message also carries a Steer button and a ⋯ menu with Edit, which takes it off the queue and into the composer, Copy, which puts its text on the clipboard without the attachment block and leaves it queued, and Remove, which drops it and its attachments.

In the composer

Typing @ opens the file-and-context picker and / opens the command list. While either popup is up, ↑ / ↓ move the selection, Enter or Tab accepts it, and Esc dismisses it.

Answering the agent's questions

When the agent asks a question, it waits: a question card appears above the composer, and the agent carries on as soon as you answer it. The card has its own keys:

The Other row has the number after the last option; pressing it, like arrowing onto it, puts the cursor in the answer field so you can type straight away, and a free-text question opens with the cursor already there. Typing in the composer answers the current question too, and the × on the card hands the agent whatever you have answered so far and lets it continue. A skipped or dismissed question comes back to the agent as "no answer", and it carries on with its best judgment rather than asking again. Closing Qubis mid-question is fine: the agent keeps waiting, and the card is back when you reopen the thread.

The card's answer field is an ordinary text field. On Windows and Linux that means Ctrl+C copies while it has focus rather than stopping — click away, press Esc (if enabled in Settings → Agent), or use the Stop button.

Layout

⇧⌘E, ⇧⌘F, ⌘L, and ⌃⌘F belong to the chat. The Solver Desk, Plugins, Scheduled, and Settings each take the content area outright, so on those pages the four do nothing rather than rearrange a page with no room for them.

Tabs and panes

Tab cycling runs the whole strip — editor, terminal, and browser tabs alike — not just whichever kind currently has focus.

Files and editing

Zoom

Text size is one size for the whole app — the editor, the UI chrome, the chat and the terminal move together.

A PDF, a schematic or an image zooms instead of the text size, but only while the keyboard is in that document in the right pane — the document itself, or a field drawn on it such as find/replace, a rename, or a viewer's own inline field. Everywhere else the chords go to the text size: the composer, the terminal, a full-width page, the command palette, the explorer, the search fields. So a PDF sitting open on the right is not rescaled while you are typing in the chat.

Viewport

The 3D viewport is mouse-driven rather than keyboard-driven; see 3D Viewport for the full control set.

Commands with no default shortcut

Reachable from the command palette:

• Toggle Sidebar
• Refresh File Explorer
• Split Editor Vertically / Horizontally, Close Split Pane
• Theme switching (nine themes)
• New Ferro Case, New NVPOST
• Open Solver Desk; Start / Restart / Stop Solver Daemon; Open Solver Daemon Log
• Git: Stage / Unstage Current File, Discard Changes, Refresh
• Check for Updates

On Windows and Linux, Go to Line... and Toggle Right Pane Maximized join this list — their chords use ⌃ and do not exist there.
