Plain J and K step the PR review guide again after you click its prose beside a chat, instead of being typed into the composer.

Problem

With the review guide open in the right panel (or the narrow-layout sheet) beside a chat, clicking the guide's prose leaves focus on the page body. The chat's type-to-focus runs first, so J/K were typed into the composer and the guide never moved.

Change

  • The guide advertises jk through the attribute the right-panel launcher already used for the same problem, renamed to data-claimed-keys (now matched case-sensitively; the launcher lists both cases). Type-to-focus leaves claimed letters alone.
  • PullRequestGuideTab remembers whether the last click or focus landed in the chat column. A chat click (also while the guide loads) hands J/K back to the composer; clicks in the panel and re-showing the guide take them back.
  • The guide claims nothing while its panel is closed or inactive, or when it has a single stop. Shift+J still types J; Caps Lock with Shift (j + Shift) steps.

Fixes pingdotgg/t3code#18300

Original description by @akbarakma

Problem

Clicking review-guide prose in the chat pull request sidebar left focus on the page body. Plain J/K then typed into the composer instead of stepping the guide.

Change

Share the guide's key-ownership check with chat type-to-focus. Track chat engagement while the guide loads, keep guide navigation after panel-header clicks, and release the keys immediately when the panel starts closing. Editable fields, modifiers, competing overlays and explicit configured shortcuts retain their existing input ownership.

Rebuilt the preserved fix for the current component layout. Credit to @akbarakma for the original implementation in #18338. The committed seed and fixture reproduce the captured state; captures are uploaded separately.

Scope and approval

Fixes https://github.com/pingdotgg/t3code/issues/18300

Triaged bug via the automated issue flow. Reproduced on current main in the real web app; no duplicate with the same symptom and surface found in open issues from the last 90 days.

Verification

The browser regression failed on main because the composer received j after clicking guide prose. The focused shortcut suite now passes all four tests, including a chat click before guide arrival and header reengagement. Targeted lint and web typecheck pass. After integrating the preserved history and current main, vp test run src/components/chat/useChatShortcuts.browser.test.tsx src/components/pullRequest passed 18 files / 179 tests. The integrated tree at ce1aa4035b exactly matches the reviewed candidate; diff whitespace checks pass.

Evidence: fixture matrix, complete corrected recordings, timestamped steps, comparisons and independent rebuild. This index supersedes earlier C3/C4 still selections and approximate video-time claims. Independent proof-audit closure: SUFFICIENT; both final code reviewers returned MERGE.

Real Vite app, Linux Chrome 154, DPR 2; 1440×900 and 390×844 CSS viewports, light and dark. Narrow captures are web sheets. System sans font stack; interface/composer/code settings 16/14/13 px. Diff0 is absolute RGB difference amplified ×8; DiffT applies raw maximum-channel threshold 16/255 before ×8 amplification. No masking or alignment correction.

The core after captures use 8772272735. Final production adds only the closing activity gate, captured separately at e8de9986ed; the final guard reel uses fee1f231f6, whose difference is test-only. Earlier captures are not relabeled as final-head captures. Both narrow revisions already navigate successfully; the corrected stills demonstrate retained sheet behavior.

C6-one — 1440×900, light

C6-three — 1440×900, light

C5 — 1440×900, light: real pending query → chat click → arrival → J → prose click → J. The original WebSocket request is held then released unchanged; no response or guide DOM is substituted. Before final state: Stop 1, jj; after: Stop 2, j.

C5 before recording · C5 after recording. Before chat/release/J/prose/J at 2.757/4.882/7.141/10.286/11.362 seconds; after 2.728/4.792/7.181/9.653/10.742 seconds. Wall offsets can differ from encoded video timestamps; final states are held three seconds.

Closing evidence compares the prior candidate, not main: before closing versus fixed closing. With the real 400 ms animation, trusted J at 86 ms was lost on the prior candidate; trusted J at 249 ms reaches chat on the fix while the guide remains mounted. Passive before trace · passive after trace.

What else differs in captures: live host mergeability (Merge/Resolve conflicts), the existing branch-changed warning, C6 sidebar ages, cursor/focus/caret, H.264 compression, and a retained jj draft in the first null-before segment. All remain visible in full-frame diffs. The core clock was frozen after setup; C5 was not frozen. These captures prove behavior, not pixel equivalence.

Unverified: independent Electron runtime, terminal focus, actual IME/legacy-229 events, first mount with body focus, inside-guide editor and unchanged error/permission/banner permutations. Native mobile, providers, server contracts and connection modes are unchanged by this web routing fix. No generation or provider run was needed.

Implementation and testing: Claude Opus 5.5 and Codex gpt-6.1-sol; independent review: both models. Orchestrated through T3 Code using the Codex harness.

Takeover

Taken over from @akbarakma (#18338); main is merged in. Replaced the second key-ownership predicate (and its pullRequest→chat import, overlay check and stopCount listener gate) with the launcher's existing claimed-keys attribute; kept the chat-engagement tracking and the closing-panel release. Added re-engaging on re-show and the Caps Lock fix found in review. Dropped the committed capture fixtures scripts/fixtures/issue-18300/ (README.md · data.json · seed.py) and replaced the PR's two tests with six focused ones. The earlier captures above predate this code.

Evidence

Recordings carry on-screen key captions; stills are each recording's final state. Timestamped steps per row: full evidence sheet · fixture matrix · manifest.

Verification log
  • Tests: useChatShortcuts.browser.test.tsx 4 → 8 (2 launcher tests kept; the PR's 2 replaced by 6). The prose-click regression test fails with the fix reverted; the loading, closing, reopen, Shift+J and Caps Lock tests each fail under the matching mutation. vp run check:changed passes on ca755a0974 and on the final merge of main.
  • Review round 1: reviewer B MERGE; reviewer A FIX_FIRST (Caps Lock+Shift+J lost by both the composer and the guide). Fixed in ca755a0974 with a test. Round 2: both MERGE, no findings.
  • Proof audit: pass 1 derived R1–R8; capture 8/8 rows. Pass 2: INSUFFICIENT for R2, R4 (the panel exit animation was left at its default 0 ms, so release while the guide stays mounted during an animated close is not shown) and R7 (the before recording's first two Files openings render blank); R1, R3, R5, R6, R8 SUFFICIENT after opening every still, diff and recording and recomputing all diffs. Recapture of R2/R4/R7 is open.
  • Captures are on ca755a0974; the final head only adds a merge of main that changes none of this PR's six files and keeps the data-chat-column marker.
  • Unverified: a physical Caps Lock key (headless automation sends the equivalent j + Shift event); desktop shares the web code and was not captured separately.
  • CI: see checks on the final head.
  • Implementation, tests and review by Claude Opus 5.5 (Claude Code) and gpt-6.1-sol (Codex), orchestrated through T3 Code.

Approvability

Verdict: Approved at ca755a0

Macroscope's review found this PR approvable — This is a localized web keyboard-routing bug fix that lets the existing review guide retain J/K when engaged while preserving composer typing after chat interaction. The production changes are small and covered by focused browser regression tests, with no product-default, schema, infrastructure, security, billing, or static-analysis changes.

Walkthrough

The review guide now handles J/K navigation only when the guide is active and engaged. Chat type-to-focus routing checks claimed keys, and browser tests cover guide navigation and chat typing across focus and loading changes.

Changes: Guide keyboard handling

Layer / File(s)Summary
Set guide shortcut scope
apps/web/src/components/pullRequest/PullRequestDetailPanel.tsx, apps/web/src/components/pullRequest/PullRequestGuideTab.tsx, apps/web/src/components/pullRequest/guide/GuideTour.tsx
The Guide tab is active only when shortcuts are enabled and the tab is selected. The guide tracks whether the guide or chat column was most recently engaged. The tour handles J/K with Shift and claims those keys only when active with multiple stops.
Route guide keys from the chat
apps/web/src/components/RightPanelTabs.tsx, apps/web/src/components/chat/composerFocusRedirect.ts, apps/web/src/components/chat/useChatShortcuts.browser.test.tsx
The launcher advertises claimed keys in both cases. Composer focus routing skips keys claimed by page elements. Browser tests cover guide navigation, chat typing, and guide loading and reopening.

J/K may navigate the guide instead of entering chat after a chat click during detail loading. The timing is narrow and guide controls remain available, so this is a bounded issue to fix or accept before merging.

Security Architecture Review

Security architecture risk: 🔵 Low · up to 54c29

Guide navigation can also trigger a configured J/K project-script shortcut. Terminal permissions remain enforced, and exposure requires a matching shortcut, but a navigation key can execute a command rather than advance the guide.

Retained concerns

  • Medium · security · inferred: Guide eligibility suppresses composer insertion but does not reserve the event from chat command dispatch. With an existing unmodified J/K project-script binding, a navigation key can execute that script under the reader's terminal authority. For a noninteractive target where composer insertion previously succeeded, this is newly reachable relative to the PR base. Existing configuration and terminal authorization checks remain enforced.
Security review details

Security Blast Radius

  • inferred — The demonstrated conditional execution scope is an existing active-project script in the active thread's environment, using the reader's terminal-operate authority. The configured command determines any subsequent filesystem, network or service effects; those downstream effects were not established.

Security Findings and Attack Paths

  • inferred — An eligible navigation key can match a configured script shortcut, be consumed by ChatView's capture handler and reach terminal execution before the guide's bubbling listener. This is a conditional privileged-action routing concern, not a demonstrated arbitrary-command injection or permission bypass. No evidence established that pull-request content can create the required binding.

Trust Boundaries and Controls

  • observed — Existing controls remain: the project-action editor checks settings-write scope; script dispatch requires terminal-operate capability and a matching active script; execution checks terminal authority before opening and again before writing the command. Type-to-focus also retains exclusions for private secret-request fields, editable targets and floating UI layers.

Explanation

Directly linked issue [#18300] asks that j and k step the review guide after a click on guide text, and that the composer not receive those keys. The current whole-PR diff (mergeBase becf853d to head ca755a09) implements this path in four places:

  1. PullRequestGuideTab.tsx adds an engaged state. Window capture listeners for pointerdown and focusin set it to false when the target is inside [data-chat-column], and to true otherwise. The guide starts engaged. It becomes engaged again when the tab is re-activated. The guide receives active={active && engaged}. This covers the case where focus falls to body after a click on guide text or a stop button.
  2. GuideTour.tsx sets data-claimed-keys="jk" only when the tour is active and has more than one stop. It also accepts shiftKey for j/k. Modifier combinations with Meta, Ctrl, or Alt remain excluded. isEditableFocused still excludes editable targets.
  3. composerFocusRedirect.ts replaces the launcher-only lookup with isClaimedKey. It reads all [data-claimed-keys] elements and matches case-sensitively. A claimed key does not trigger type-to-focus. Shifted J (event.key === "J") is not in "jk", so it still types into the composer. Caps Lock with Shift (event.key === "j") reaches the guide.
  4. RightPanelTabs.tsx advertises launcher shortcuts through data-claimed-keys in both cases. PullRequestDetailPanel.tsx activates the guide only when shortcutsEnabled is true and the Guide tab is selected.

The browser tests named in the PR cover chat click before guide arrival, header re-engagement, Shift+J typing, and J navigation with lowercase j. I did not re-run these tests. I rely on the diff and the reported results. The PR states that the explicit configured shortcut priority is unverified or outside scope. [#18300] does not request configurable shortcut behavior, so this does not block the verdict. The [data-chat-column] attribute is set outside the reviewed diff. Its presence at head is inferred from the reported chat-click tests, not from a direct read.

Full details: Out of Scope Changes check

Explanation

All changed source files are in apps/web and serve the J/K routing fix for [#18300]. Each file maps to a part of that fix:

  • composerFocusRedirect.ts: generic claimed-key lookup used by type-to-focus.
  • GuideTour.tsx: claimed-key attribute and Shift+J handling for guide stepping.
  • PullRequestGuideTab.tsx: engagement tracking between guide and chat.
  • RightPanelTabs.tsx: launcher keys exposed through the same claimed-key attribute.
  • PullRequestDetailPanel.tsx: guide shortcut activation gated by shortcutsEnabled.
  • Browser test file for shortcut routing.

The Shift+J change is a small extension. It only affects event.key === "j" or "k" with Shift held, which is the Caps Lock case. Shifted J still types, as before. No unrelated feature, setting, server contract, or provider code appears in the reviewed summary. The PR description states that capture fixtures were removed in later commits. I did not inspect fixture paths at head. Those files are non-source artifacts and do not change the verdict.

Taking over this one as maintainer for batch pull-request-03. I will preserve the original intent, update it for current main, verify the keyboard routing, and push follow-up commits here. Thanks @akbarakma for the fix and interaction evidence.

Published the takeover at af68de7. Focused checks and current-head CI pass; both independent reviewers returned no blockers. The earlier cancelled fingerprint workflow was superseded by a later successful run on this same head. Before/after evidence and platform limits are in the updated body.

The retained CodeRabbit project-script concern follows the intended explicit-binding priority, as does the withdrawn copy-number finding: a configured bare J/K command consumes the event before the built-in tour shortcut. The browser regression verifies that priority, and existing terminal authorization remains enforced. Overriding an explicit user binding is outside this fix.

Thanks @akbarakma for the original fix. Left unmerged.

Preserve chat engagement when the guide first mounts.

If Guide is selected while pull-request detail loads, PullRequestDetailPanel does not mount this tab until loading finishes. A chat transcript click during loading cannot reach the new listeners. useState(true) then makes the guide claim J/K, so pressing j advances the guide instead of typing into the composer. Track chat engagement before the guide tab mounts, and test a chat click during detail loading. (raw.githubusercontent.com)

  • Merge remote-tracking branch 'origin/main' into pr-18338803fa1d

Thanks @akbarakma for the earlier fix and evidence. This PR is stale: its last update was October 27, and main has changed the affected files since its base. #32302 by @flambo addresses the same J/K composer collision and also handles returning focus and the maximized panel, so I’m closing this as a duplicate.
