Keyboard shortcut to move focus between panes (terminal, chat, diff) without toggling them

Confirming this on Windows 11 (Desktop app, Code tab, 2.1.247). The issue currently carries platform:macos, but the gap is identical on Windows: Nothing in the Code tab's shortcut table moves focus to the chat composer, so getting back to it after reading a diff or working in another pane means reaching for the mouse.

One data point that narrows the ask: Ctrl+Tab / Ctrl+Shift+Tab (cycle sessions) does restore composer focus on Windows. Cycling away from a session and back is a usable workaround, and more usefully it shows the app already has a working "focus the composer" path — it just isn't reachable on its own. A standalone focus chat input action would largely mean exposing what session switching already calls, rather than building new behavior.

That also separates this request from the neighbouring focus reports: This is not focus being lost (#80743, #88317). Focus lands where it should; there is simply no key that asks for it.

On the rebindability note in the description: #86204, which asked for keybindings.json support in the desktop chat input, was closed on 2026-08-25 as a duplicate of #74655. That target covers the submit key specifically, so general rebindability of desktop shortcuts currently has no active owner. Worth folding into this issue if focus actions land.

Documentation cross-check as of 2026-08-30: The Code tab shortcut table lists no focus-movement entry, and keybindings.json exposes no focus action in any context.

Filed the narrow half separately as #90743: A dedicated shortcut that focuses the composer and does nothing else, with how OpenCode, Antigravity, Codex, and Copilot Chat each bind it. This issue stays the broader pane-navigation request; the two are meant to be read together rather than as duplicates.

Still unaddressed as of 2026-09-23 (Claude Desktop 2.7032.0.0, Windows 11):

• The Code tab shortcut table on the Desktop page has "Close focused pane" but still no way to move focus between panes.
• I found no pane-focus navigation in the Desktop changelog from 1.40609.0 through 2.7032.0.

Meanwhile the number of panes has grown: 1.44121.1 added a Split View submenu, and side panes (diff, terminal, plan, preview) can open in their own window. Related newer reports: #92943 (no way to move keyboard focus into the diff/review panel, currently labelled area:tui) and #92395 (the terminal panel steals focus on every shell tool call).

Status as of 2026-10-08 (Claude Desktop 2.19675.1.0, Windows 11). I read this from the shipped renderer bundle and did not test it in the app:

• Ctrl+] / Ctrl+[ are bound to "Focus next split view" / "Focus previous split view" and appear in the in-app shortcut list. They only move focus between split-view session panes. They don't reach the terminal, the diff, or other side panes.
• A focus-region module adds F6 / Shift+F6 ("Focus next/previous page area"). It also adds command-menu entries "Jump to terminal", "Jump to side panel", "Jump to preview" and "Jump to input". The module loads only behind a feature gate, and the jump commands have no default key binding.
• The shortcut table on the Desktop page lists none of these. "Close focused pane" is still its only pane-focus row.

So the pieces exist. For this request, what's missing is ungated default keys that move focus between chat, terminal and diff without toggling them, plus their documentation.
