# Tech tracking
tech-stack:
  added: []
  patterns:
    - "Record-style key capture pattern: click to record, keydown to capture, Escape/blur to cancel"
    - "Conflict detection banner with overwrite/cancel resolution"
    - "Static SHORTCUT_META metadata map for UI labels, categories, scopes, and defaults"

key-files:
  created:
    - frontend/src/components/config-page/shortcut-capture.ts
  modified:
    - frontend/src/components/config-page/config-page.ts

key-decisions:
  - "Place Keyboard Shortcuts as a config-section between Track List Columns and Library sections"
  - "Use static SHORTCUT_META record on ConfigPage class for action metadata rather than importing from backend"
  - "Conflict detection shows banner inline rather than dialog — simpler interaction pattern"

patterns-established:
  - "shortcut-capture component: reusable record-style key binding widget"

# Phase 9 Plan 4: Keyboard Shortcuts Settings UI Summary

**Record-style shortcut capture component with categorized settings section, inline conflict detection banner, and per-shortcut/global reset controls**

## Performance

- **Duration:** 5 min
- **Started:** 2026-03-07T02:52:35Z
- **Completed:** 2026-03-07T02:58:26Z
- **Tasks:** 2
- **Files modified:** 2

## Accomplishments
- shortcut-capture web component with recording mode, Escape cancel, blur cancel, and per-shortcut reset
- Keyboard Shortcuts section in config page with Player, Navigation, App category grouping
- All 16 default shortcuts listed with human-readable labels and scope indicators
- Conflict detection warns before overwriting with Overwrite/Cancel resolution
- Reset All to Defaults button for global shortcut reset

## Task Commits

Each task was committed atomically:

1. **Task 1: Create shortcut-capture web component** - `3914369` (feat — bundled into 09-03 commit by concurrent agent)
2. **Task 2: Add Keyboard Shortcuts section to config page with conflict detection** - `0451fb3` (feat)

## Files Created/Modified
- `frontend/src/components/config-page/shortcut-capture.ts` - Record-style key capture widget with buildKeyString integration
- `frontend/src/components/config-page/config-page.ts` - Added Keyboard Shortcuts section with category grouping, conflict detection, reset controls

## Decisions Made
- Placed Keyboard Shortcuts section between Track List Columns and Library (natural position before infrastructure settings)
- Used static `SHORTCUT_META` map on ConfigPage for label/category/scope/default metadata — keeps UI concerns local rather than pulling from backend
- Conflict detection uses an inline banner below the shortcuts list rather than a modal dialog — simpler and less disruptive

## Deviations from Plan

### Auto-fixed Issues

**1. [Rule 3 - Blocking] shortcut-capture.ts already committed by concurrent Plan 03 agent**
- **Found during:** Task 1 (commit attempt)
- **Issue:** The shortcut-capture.ts file was already in the working tree when Plan 03's agent ran `git add`, so it was bundled into commit `3914369` (feat(09-03))
- **Fix:** Verified the file content matches the plan specification exactly — no re-creation needed. Proceeded to Task 2.
- **Files modified:** None (file already correct)
- **Verification:** `npx tsc --noEmit` passes, file content verified
- **Committed in:** 3914369 (09-03 commit)

---

**Total deviations:** 1 auto-fixed (1 blocking)
**Impact on plan:** Task 1's file was pre-committed by a concurrent agent. Content is correct; only the commit attribution differs. No scope creep.

## Issues Encountered
None

## User Setup Required

None - no external service configuration required.

## Next Phase Readiness
- Shortcuts settings UI complete — users can view, rebind, and reset all keyboard shortcuts
- Ready for Plan 05 (shortcuts integration testing) or other remaining plans
- shortcut-capture component is reusable for any future key-binding UI needs

## Self-Check: PASSED

- [x] shortcut-capture.ts exists
- [x] config-page.ts exists
- [x] 09-04-SUMMARY.md exists
- [x] Commit 3914369 exists (Task 1 — bundled in 09-03)
- [x] Commit 0451fb3 exists (Task 2)
