+# Phase 9: Scan Cancellation & Keyboard Shortcuts - Context
+
+**Gathered:** 2026-03-06
+**Status:** Ready for planning
+
+<domain>
+## Phase Boundary
+
+Users can control library scans (cancel/pause/resume) and operate the entire app via configurable keyboard shortcuts. Scans stop gracefully without database corruption, paused scans resume without re-processing. Keyboard shortcuts work out of the box with sensible defaults, are fully customizable via a settings UI, context-aware across three scopes, and suppressed during text input.

+## Implementation Decisions
+
+### Default key bindings
+- Hybrid style: Space/arrows for player controls (no modifier), Ctrl+key for app actions
+- Up/Down arrows adjust volume, Left/Right seek within track
+- Both `/` and `Ctrl+F` focus the search box
+- `Q` toggles the queue panel
+- `S` for shuffle, `R` for repeat (single-key player controls)
+- `Ctrl+A` for select-all in any multi-select context (track lists, etc.)
+- All bindings are configurable — the above are defaults
+- Claude fills in remaining defaults (mute, etc.) using common media player conventions
+
+### Shortcut settings UI
+- Record-style key capture: click a shortcut row, press the new key combo, it captures live
+- Conflicts show a warning with the conflicting action — user chooses to overwrite (old becomes unbound) or cancel
+- Shortcuts grouped by category (Player, Navigation, App) in the settings view
+- "Reset to defaults" button resets all shortcuts; individual per-shortcut reset also available
+- Lives as a "Keyboard Shortcuts" tab within the existing settings dialog
+
+### Context scoping
+- Three scopes: Global (always active), Panel-specific (when a panel has focus), Text Input (shortcuts suppressed)
+- Global scope: player controls (Space, arrows, S, R, Q, etc.) fire regardless of which panel is focused
+- Panel-specific scope: track list gets Enter-to-play and Delete-to-remove when focused
+- Text Input scope: only Escape works (blurs the text input) — all other shortcuts suppressed
+- No visual scope indicator — relies on natural browser focus behavior; users learn through use
+
+### Scan control UX
+- Pause and Cancel buttons placed next to the existing status label, above the existing progress bar in the scanner UI
+- On cancel: prompt the user — "Keep X tracks found so far, or discard?" — gives user control over partial results
+- On resume after pause: skip already-processed files and continue with remaining — no duplicate work
+- Scan control is buttons-only — no keyboard shortcuts for cancel/pause (scans are infrequent)
+
+### Claude's Discretion
+- Remaining default key assignments not explicitly discussed (mute, volume step size, etc.)
+- Scan progress detail level and error handling during scan
+- Loading/disabled states for scan control buttons
+- Visual design of the shortcut settings UI (spacing, grouping headers, etc.)
+- How the cancel confirmation dialog looks and behaves
+
+</decisions>
+
+<specifics>
+## Specific Ideas
+
+- Hybrid key style inspired by media players (Foobar2000/Winamp feel for player controls, standard app conventions for Ctrl+key actions)
+- Both `/` and `Ctrl+F` for search — power users get slash, everyone knows Ctrl+F
+- Record-style key capture like VS Code's keybinding editor
+- Cancel prompt on scan gives user control without losing work
+

+## Deferred Ideas

+None — discussion stayed within phase scope
