Problem

There is no keyboard shortcut to move between the tabs in the right panel. With a few side chats open (/btw, /side), switching between them means clicking each tab. The bindable commands cover opening, closing, reopening and maximizing panel tabs, but not moving between them.

Change

  • Adds two keybinding commands, rightPanel.nextTab and rightPanel.previousTab, bound by default to mod+alt+right and mod+alt+left. They activate the next or previous tab of the open right panel in tab order, wrapping at either end. Side chats, previews, diffs, files and terminals are all included. With the panel closed or only one tab open, the handler returns false, so the keys fall through unchanged.
  • selectAdjacentRightPanelSurface in rightPanelStore.ts picks the tab. The handler activates it through the existing activateRightPanelSurface, so tab-specific side effects (preview tab, terminal focus, diff open) behave as they do on click.
  • useChatShortcuts ignores keys from inside a side chat pane. It now lets these two commands through, so they work while typing in a side chat's composer.
  • Added both commands to the desktop preview's forwarded shortcuts (handled as menu actions in ChatView) and to the HTML render frame's shortcut set, so they also work with focus in a browser or HTML preview tab.
  • Documented the shortcuts in docs/user/keybindings.md.

Mobile has no hardware-keyboard panel tabs, so it is unaffected. The Pull requests page keeps its own panel handler and is not changed.

Scope and approval

There is no prior issue or Ideas discussion for this. It is a new pair of commands with new default bindings, so I understand it may need maintainer approval of direction before review. I'm happy to open a discussion, or to drop the defaults and ship only the commands so users bind them themselves.

Verification

  • Added a case to apps/web/src/rightPanelStore.test.ts. With a file tab and two side chats open, it checks that next and previous step in tab order, wrap at both ends, and return nothing with a single tab or with the panel closed.
  • vp run check:changed passes: format, lint, knip, typecheck of affected packages, tests beside the changes (including the keybinding and settings logic tests), and the React compiler check.
  • Built the arm64 macOS app with vp run dist:desktop:dmg:arm64 and confirmed the bundle contains the new commands and default bindings.
  • Not yet checked by hand in a running app, so there is no recording. The change has no visual difference to capture.

Made with Claude Opus 5.5 in Claude Code, running in T3 Code.

Approvability

Verdict: Needs Human Approval

Macroscope's review found this PR requires human approval — Adds configurable shortcuts to cycle through open right-panel tabs, including from side chats and previews. Human review is required because mod+alt+left/right are enabled as new product defaults.

Walkthrough

Adds next- and previous-tab commands for right-panel surfaces. The commands select adjacent surfaces, wrap at either end, and are available through keyboard shortcuts, side-chat panes, desktop menu actions, and supported shortcut-forwarding paths.

Changes: Right-panel navigation

Layer / File(s) Summary
Selector and keybinding contract
apps/web/src/rightPanelStore.ts, apps/web/src/rightPanelStore.test.ts, packages/contracts/src/keybindings.ts, packages/shared/src/keybindings.ts
Adds a selector that returns the next or previous surface, wrapping around the surface list. It returns no surface when fewer than two are open or none is active. Tests cover these cases. Adds command names and default keybindings.
Shortcut and menu execution
apps/web/src/components/chat/useRightPanelActions.ts, apps/web/src/components/chat/useChatShortcuts.ts, apps/web/src/components/ChatView.tsx
Registers next- and previous-tab shortcuts and routes them to adjacent-surface activation. Side-chat panes handle these commands locally. Desktop menu actions use the same activation path.
Command forwarding and documentation
apps/web/src/components/ReopenClosedViewShortcut.tsx, apps/web/src/components/files/BrowserDocumentFrame.tsx, docs/user/keybindings.md
Adds both commands to desktop preview and HTML-render shortcut lists. Documents the keybindings, wrapping behavior, side-chat availability, and settings names.

The feature adds next and previous right-panel tab shortcuts. In a browser on macOS Chrome the default keys will switch browser tabs instead, and custom composer-focus bindings will not fire in side chats. Neither blocks the main workflow, and users can rebind the shortcuts.

The CI run on the current head (7df639b) was cancelled by the re-run on the earlier commit (99d0f06), since both share the ci-34437 concurrency group. Could someone re-run CI on the current head? Thanks!

Do not consume preview shortcuts when there is no adjacent tab.

With a single preview tab, the desktop preview manager prevents the key event before forwarding it. The adjacent-tab action then returns false, but the preview page cannot receive the original key. Register these shortcuts only while the panel has another tab, or preserve the page event when navigation cannot run. (raw.githubusercontent.com)

Unverified finding

Forward tab shortcuts from editable HTML content.

The HTML-render bootstrap excludes input, textarea, select, and contenteditable targets before forwarding keys. The new shortcuts therefore do nothing while users type in an HTML-rendered form. Extend the forwarding contract for these commands without intercepting ordinary text input. (raw.githubusercontent.com)

Resolve composer focus for the side chat.

If a user binds a tab command with when: "composerFocus", it does not run from the side-chat composer. The parent ChatView sets composerFocus to false for side-chat elements. Resolve the side-chat focus context before matching these commands.
