🤖 Claude Opus 5.5 on behalf of Oliver

In a thread with the PR guide open beside the chat, J and K did nothing unless a button in the guide (like the "Stop 1 of 3" picker) had focus. Click the guide's text, press J, and the letter landed in the composer instead. With the PR panel maximized, J and K could also type into the hidden composer.

Now a click anywhere in the guide lets J and K step it, and so does a maximized panel. Other letters still go to the composer, and clicking the composer gives J and K back to typing.

Problem

Clicking guide text focuses nothing, so focus sits on the page body. The chat's type-to-focus handler sends any plain letter typed on the body into the composer, and it runs before the guide's J/K listener. Returning to the window had the same effect: the composer takes focus back from anything that isn't a field, a dialog, or a terminal.

A maximized panel makes the chat column inert, so focus drops to the body when a thread opens maximized (a saved maximized panel, or the desktop app opening a link maximized). Type-to-focus still wrote J and K into the hidden composer.

Stepping from the guide's own buttons (Previous/Next stop, "Next:", or a stop in the "Stop 1 of 3" picker) remounts the stop, so the clicked button disappears and focus falls to the body. A window return then moved focus into the composer, and K typed there.

Fix

  • The guide's scroll area is focusable (tabIndex={-1}, no focus ring) and declares its keys with the standard aria-keyshortcuts="J K". A click on its text now puts focus there.
  • Type-to-focus leaves a key alone when an element around the focus declares it in aria-keyshortcuts.
  • Type-to-focus and paste-to-focus skip the composer while its chat column is maximized away.
  • Returning to the window keeps focus inside such an element instead of moving it to the composer. While maximized, the inert column already keeps the composer from taking focus back.
  • A step started from inside the stop moves focus to the guide's scroll area first, so it stays in the guide. Focus elsewhere, including the side rail of stops, is left alone.
  • With Caps Lock on, J and K still step the guide, matching the key check in type-to-focus.

This follows focus instead of tracking clicks, so the guide owns J and K only while you are in it. Opening a thread still focuses the composer, so J types there until you click the guide.

Supersedes #18338. That PR covers the same click-on-text case by having the guide claim J and K for the whole page while it is shown, then remembering whether your last click was in the chat column so it can hand the keys back. This one needs neither, because focus already says where you are. It also covers returning to the window, which #18338 does not: the composer refocuses on window return, and the guide ignores keys while a field has focus.

Scope and approval

Fixes the accepted, triaged bug #18300. Julius confirmed it on main in this comment and suggested having type-to-focus skip the key while focus is in the guide. This PR does that, keyed on focus.

It also covers the maximized-panel case folded in from #18600 (comment). Since that comment, #25877 made the maximized chat column inert, which handles the Maximize button and the keybinding: both leave focus on a panel button. The case left was a thread that opens already maximized, which this PR fixes by skipping type-to-focus while the column is maximized away.

Verification

  • PullRequestGuideTab.browser.test.tsx renders the guide tab next to the real chat shortcut listener. It presses J while the chat column is maximized away, then clicks guide text and presses K, clicks Next stop and presses J, then K, a Caps Lock J, and A. Without the maximized fix the first J types into the composer, and without the step-focus fix the J after Next stop does too. Both fail before and pass here. A row in ChatView.logic.browser.test.ts covers the window-return rule.
  • In the real web app (dev server, Replay thread with a linked PR and a stored 3-stop guide):
    • Clicking guide text, then J/J/K, goes stop 1 → 2 → 3 → 2 with an empty composer. After a window focus event, focus stays in the guide and J still steps. A still types into the composer.
    • Reopening a thread whose panel was left maximized: before, J/J/K typed jjk into the hidden composer and the guide stayed on stop 1. Now they go 1 → 2 → 3 → 2 and the composer stays empty. Maximizing with the button or the rightPanel.toggleMaximized keybinding steps too. After restoring, typing on the page goes to the composer again.
    • Clicking Next stop, then J, then a window focus event, then K: before, K typed into the composer. Now focus stays in the guide and K steps.
  • vp run check:changed passes.

The standalone Pull requests page has no composer, so only the step-focus fix applies there. Mobile has no hardware-key stepping for the guide, so nothing changes there.

Fixes #18300

Fixed in 4a2a04ccb2. The guide now lowercases the key before its J/K check, so a Caps Lock J or K steps the guide instead of being dropped. Shift+J still goes to the composer, as before. The J/K browser test now dispatches a Caps Lock J (no Shift) and fails without the fix.

Walkthrough

The guide panel declares J/K keyboard shortcuts and handles them case-insensitively. Chat focus logic checks shortcut declarations before redirecting typed keys and preserves focus in shortcut regions. Browser tests cover guide navigation, composer typing, and focus preservation.

Explanation

The description covers the problem, the fix, scope and approval, and detailed verification. The “Fix” heading serves the template’s “Change” section, and the description includes UI evidence and the agent details.

Full details: Linked Issues check

Explanation

#18300 requires J/K to step the Guide tab after the user clicks guide text, without sending those keys to the composer. GuideTour.tsx makes the scroll area focusable and declares aria-keyshortcuts="J K". composerFocusRedirect.ts leaves matching keys with that region. GuideTour.goTo restores focus to the scroll area after a stop change when focus was inside the guide outside the stop rail. The keyboard handler accepts uppercase and lowercase J/K. The added browser test covers guide-text focus, stop changes, Caps Lock J, and an unrelated letter reaching the composer. The window-focus change preserves focus in a shortcut region.

Full details: Out of Scope Changes check

Explanation

The changes support #18300's Guide-tab keyboard behavior. The maximized-away guard prevents type-to-focus from sending keys to a composer that is hidden, which supports the reported maximized Guide scenario. Its effect on other plain character keys is limited to that hidden-composer state. The retained failed-guide retry test is unchanged in the PR diff, so it is not an out-of-scope change.

Keep keyboard focus in the guide after a stop step.

Stepping from the "Next stop" or "Next:" button in GuideStop unmounts that button, because GuideTour keys the stop by position. The browser then moves focus to the document body, so keyboard focus leaves the guide. The J/K listener still steps the guide from the body. The Tab order restarts from the top of the page.

Move focus to the guide container, scrollRef, when the focused control is removed by a step. The container is already tabIndex={-1}. The existing browser test presses J J K after a click on guide text, so it does not cover a step started from a button. Add a case that starts from the Next button.

âś… Confirmed as addressed by @flamboh

Note

🤖 Claude Opus 5.5 on behalf of Oliver

Fixed in 782138360c. A step that starts from inside the stop (Previous/Next stop, "Next:", or the "Stop 1 of 3" picker) now moves focus to the guide's scroll area before the stop remounts, so focus stays in the guide. The side rail of stops stays mounted, so focus there is left alone. The J/K browser test now clicks Next stop and presses J; it fails without the fix.

@flamboh Thanks for the fix. Moving focus before the stop remounts addresses the reported issue. The test also covers pressing J after Next stop.

Limit J/K stepping to focus inside the guide.

The key check now accepts Caps Lock uppercase J and K. The document listener still steps the guide when a non-editable element outside the guide has focus, because the only focus condition is the editable-element check. This is a routing mismatch with the PR's stated rule that guide focus determines where these keys go. Caps Lock users reach it through the new uppercase path, and lowercase keys already reach it.

The fix requires a focus-scope decision. Add a guard that checks whether document.activeElement is inside scrollRef. Keep this check separate from the editable-element check. Confirm the intended behavior for focus on the page body and other non-editable controls before you change lowercase behavior.

Leaving this as is. Main's listener already steps on J/K whenever focus is on any non-editable element, so this PR doesn't change who gets the keys outside the guide; it only stops the composer from grabbing them. Caps Lock only makes uppercase match lowercase.

Requiring focus inside the guide would break the standalone PR screen, where nothing in the guide has focus when it opens and J/K work today.

@flamboh You're right. The existing listener handles lowercase J/K outside the guide, and the new uppercase path follows the same routing. Restricting focus to the guide could break the standalone screen, so I withdraw the suggestion.

Note

Written by claude-opus-5-5 on behalf of Maria

Merged current main into the branch (f6ecfa9b14, merge commit, no rebase) to clear the conflict in ChatView.logic.ts and its browser test:

  • shouldRefocusComposerOnWindowFocus now uses main's [data-workspace-keyboard-focus] selector plus this PR's [aria-keyshortcuts].
  • ChatView.logic.browser.test.ts keeps both the new shortcut-region test and main's bare-key-press test.

No other changes. The open review findings (Caps Lock J/K, focus after a stop button) were already fixed on the branch. vp run check:changed and the two touched browser test files pass.
