# Agent 5: Keyboard Shortcuts Implementation ## Overview Implementation of Apple Preview-style keyboard shortcuts for search functionality in DocumentView.vue. ## Files Modified - `/home/setup/navidocs/client/src/views/DocumentView.vue` ## Implementation Summary ### Keyboard Shortcuts Implemented | Shortcut | Action | Platform | |----------|--------|----------| | `Cmd + F` (Mac) / `Ctrl + F` (Win/Linux) | Focus search box and select text | Cross-platform | | `Enter` | Navigate to next search result (when not in input) | All | | `Cmd/Ctrl + G` | Navigate to next search result | Cross-platform | | `Shift + Enter` | Navigate to previous search result | All | | `Cmd/Ctrl + Shift + G` | Navigate to previous search result | Cross-platform | | `Escape` | Clear search and close jump list | All | | `Cmd/Ctrl + Alt + F` | Toggle search jump list (sidebar) | Cross-platform | ### Key Features 1. **Cross-Platform Detection**: Automatically uses Cmd on Mac, Ctrl on Windows/Linux 2. **Prevents Default Browser Find**: Cmd/Ctrl+F won't open browser's native find dialog 3. **Context-Aware**: Enter key performs search when input is focused, navigates results otherwise 4. **Global Shortcuts**: Work anywhere when the document is in focus 5. **Apple Preview-Style**: Matches familiar keyboard navigation patterns from macOS Preview app ### Changes Required #### 1. Template Changes (Line ~49) **Add `ref="searchInputRef"` to the search input:** ```vue ``` #### 2. Script Setup - Add Ref Declaration (After line ~427) ```javascript // Use hysteresis to prevent flickering at threshold const COLLAPSE_THRESHOLD = 120 // Collapse when scrolling down past 120px const EXPAND_THRESHOLD = 80 // Expand when scrolling up past 80px // Search input ref for keyboard shortcuts const searchInputRef = ref(null) // Computed property for selected image URL const selectedImageUrl = computed(() => { if (!selectedImage.value) return '' return getImageUrl(documentId.value, selectedImage.value.id) }) ``` #### 3. Add Keyboard Handler Function (Before onMounted, around line 1180) ```javascript /** * Handles keyboard shortcuts for search functionality (Apple Preview-style) */ function handleKeyboardShortcuts(event) { const isMac = navigator.platform.toUpperCase().indexOf('MAC') >= 0 const cmdOrCtrl = isMac ? event.metaKey : event.ctrlKey const isInputFocused = document.activeElement === searchInputRef.value // Cmd/Ctrl + F - Focus search box if (cmdOrCtrl && event.key === 'f') { event.preventDefault() if (searchInputRef.value) { searchInputRef.value.focus() searchInputRef.value.select() } return } // Escape - Clear search and blur input if (event.key === 'Escape') { if (searchQuery.value || isInputFocused) { event.preventDefault() clearSearch() if (isInputFocused && searchInputRef.value) { searchInputRef.value.blur() } jumpListOpen.value = false } return } // Enter or Cmd/Ctrl + G - Next result if (event.key === 'Enter' && !isInputFocused) { if (totalHits.value > 0) { event.preventDefault() nextHit() } return } if (cmdOrCtrl && event.key === 'g' && !event.shiftKey) { if (totalHits.value > 0) { event.preventDefault() nextHit() } return } // Shift + Enter or Cmd/Ctrl + Shift + G - Previous result if (event.key === 'Enter' && event.shiftKey && !isInputFocused) { if (totalHits.value > 0) { event.preventDefault() prevHit() } return } if (cmdOrCtrl && event.key === 'G' && event.shiftKey) { if (totalHits.value > 0) { event.preventDefault() prevHit() } return } // Cmd/Ctrl + Option/Alt + F - Toggle jump list if (cmdOrCtrl && event.altKey && event.key === 'f') { if (hitList.value.length > 0) { event.preventDefault() jumpListOpen.value = !jumpListOpen.value } return } } ``` #### 4. Register Listener in onMounted (Around line 1180) ```javascript onMounted(() => { loadDocument() // Register global keyboard shortcut handler window.addEventListener('keydown', handleKeyboardShortcuts) // Handle deep links (#p=12) const hash = window.location.hash // ... rest of existing code }) ``` #### 5. Clean Up Listener in onBeforeUnmount (Around line 1246) ```javascript // Clean up listeners onBeforeUnmount(() => { if (rafId) { cancelAnimationFrame(rafId) } if (scrollTimeout) { clearTimeout(scrollTimeout) } window.removeEventListener('scroll', handleScroll) window.removeEventListener('hashchange', handleHashChange) window.removeEventListener('keydown', handleKeyboardShortcuts) // ADD THIS LINE }) ``` ## Testing Checklist 1. **Focus Search Box** - [ ] Press `Cmd+F` (Mac) or `Ctrl+F` (Windows/Linux) - [ ] Search input should receive focus - [ ] Existing text should be selected - [ ] Browser's native find dialog should NOT open 2. **Navigate Results** - [ ] Type a search query and press Enter - [ ] Press `Enter` or `Cmd/Ctrl+G` → Should go to next result - [ ] Press `Shift+Enter` or `Cmd/Ctrl+Shift+G` → Should go to previous result - [ ] Current result should be highlighted with pink background - [ ] Page should scroll to show current result 3. **Clear Search** - [ ] With search active, press `Escape` - [ ] Search should clear - [ ] Highlights should be removed - [ ] If search input was focused, it should blur 4. **Toggle Jump List** - [ ] Perform a search with multiple results - [ ] Press `Cmd/Ctrl+Alt+F` - [ ] Jump list (search sidebar) should toggle open/closed 5. **Context Awareness** - [ ] With search input focused, `Enter` should execute search - [ ] With search input NOT focused, `Enter` should navigate to next result - [ ] Shortcuts should not interfere with other inputs or modals ## Implementation Notes ### Cross-Platform Detection The implementation uses `navigator.platform` to detect macOS and automatically maps shortcuts: - Mac: Uses `event.metaKey` (Cmd key) - Windows/Linux: Uses `event.ctrlKey` (Ctrl key) ### Event Prevention All shortcuts call `event.preventDefault()` to prevent default browser behavior, particularly important for `Cmd/Ctrl+F` which would normally open the browser's find dialog. ### Context-Aware Enter Key The Enter key behavior changes based on whether the search input is focused: - **Input focused**: Executes search (existing behavior) - **Input not focused**: Navigates to next result (new behavior) ### Memory Management Keyboard event listener is properly cleaned up in `onBeforeUnmount` to prevent memory leaks when the component is destroyed. ## Code Structure The implementation follows Vue 3 Composition API patterns: 1. **Reactive ref**: `searchInputRef` for accessing the DOM element 2. **Event handler function**: `handleKeyboardShortcuts` for centralized shortcut logic 3. **Lifecycle hooks**: `onMounted` to register, `onBeforeUnmount` to clean up 4. **Existing functions**: Reuses `nextHit()`, `prevHit()`, `clearSearch()`, `performSearch()` ## UI Improvements The search input placeholder now includes a hint: ``` "Search in document... (Cmd/Ctrl+F)" ``` This provides visual feedback to users that keyboard shortcuts are available. ## Future Enhancements Potential improvements for future iterations: 1. Add keyboard shortcut help modal (press `?` to show all shortcuts) 2. Implement `Cmd/Ctrl + A` to select all results 3. Add `Cmd/Ctrl + C` to copy current result context 4. Support arrow keys for result navigation 5. Add visual indicator when keyboard shortcuts are active 6. Persist user's keyboard shortcut preferences ## Related Files - **Implementation Reference**: `/home/setup/navidocs/KEYBOARD_SHORTCUTS_CODE.js` - **Detailed Patch Guide**: `/home/setup/navidocs/KEYBOARD_SHORTCUTS_PATCH.md` - **Target File**: `/home/setup/navidocs/client/src/views/DocumentView.vue` ## Agent Handoff **Status**: Implementation code ready **Next Agent**: Can proceed with integration testing and UI polish **Blockers**: None - all existing search functionality preserved **Dependencies**: Existing search functions (`nextHit`, `prevHit`, `clearSearch`, `performSearch`) --- *Implementation completed by Agent 5 of 10* *Date: 2025-11-13* *Task: Implement keyboard shortcuts for Apple Preview-style search*
