(Shift+/) : Show keyboard shortcuts help - Added process navigation shortcuts: - j : Select next process - k : Select previous process - Space : Toggle selection of focused process - Auto-scroll to focused process - Created KeyboardShortcutsHelp modal component: - Organized shortcuts by category - Visual kbd elements for keys - Info about input field behavior - Added keyboard shortcuts button to processes page header - Added isFocused prop to ProcessCard with accent ring styling - Added data-process-id attributes for keyboard navigation 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude --- app/processes/page.tsx | 146 ++++++++++++++++++++++-- components/process/ProcessCard.tsx | 6 +- components/ui/KeyboardShortcutsHelp.tsx | 111 ++++++++++++++++++ lib/hooks/useKeyboardShortcuts.ts | 88 ++++++++++++++ 4 files changed, 338 insertions(+), 13 deletions(-) create mode 100644 components/ui/KeyboardShortcutsHelp.tsx create mode 100644 lib/hooks/useKeyboardShortcuts.ts diff --git a/app/processes/page.tsx b/app/processes/page.tsx index f225d74..9a64f19 100644 --- a/app/processes/page.tsx +++ b/app/processes/page.tsx @@ -1,20 +1,25 @@ 'use client'; -import { useState, useCallback } from 'react'; +import { useState, useCallback, useRef, useEffect } from 'react'; import { useProcesses } from '@/lib/hooks/useSupervisor'; import { ProcessCard } from '@/components/process/ProcessCard'; import { GroupView } from '@/components/groups/GroupView'; import { GroupSelector } from '@/components/groups/GroupSelector'; import { BatchActions } from '@/components/process/BatchActions'; import { ProcessFilters } from '@/components/process/ProcessFilters'; -import { RefreshCw, AlertCircle, CheckSquare } from 'lucide-react'; +import { RefreshCw, AlertCircle, CheckSquare, Keyboard } from 'lucide-react'; import { Button } from '@/components/ui/button'; +import { useKeyboardShortcuts } from '@/lib/hooks/useKeyboardShortcuts'; +import { KeyboardShortcutsHelp } from '@/components/ui/KeyboardShortcutsHelp'; import type { ProcessInfo } from '@/lib/supervisor/types'; export default function ProcessesPage() { const [viewMode, setViewMode] = useState<'flat' | 'grouped'>('flat'); const [selectedProcesses, setSelectedProcesses] = useState>(new Set()); const [filteredProcesses, setFilteredProcesses] = useState([]); + const [showShortcutsHelp, setShowShortcutsHelp] = useState(false); + const [focusedIndex, setFocusedIndex] = useState(-1); + const searchInputRef = useRef(null); const { data: processes, isLoading, isError, refetch } = useProcesses(); const handleFilterChange = useCallback((filtered: ProcessInfo[]) => { @@ -48,6 +53,111 @@ export default function ProcessesPage() { setSelectedProcesses(new Set()); }; + // Get displayedProcesses for keyboard navigation + const displayedProcesses = filteredProcesses.length > 0 || !processes ?
