Detailed Shortcuts

​
File Management

Opens the command palette-style file search modal.Implementation: page.tsx:382-388
if ((e.ctrlKey || e.metaKey) && e.key === 'k') {
  e.preventDefault();
  setShowFileSearchModal(true);
  setSearchQuery('');
  setFileSearchIndex(0);
  setTimeout(() => fileSearchInputRef.current?.focus(), 50);
}
What happens:
  • Opens the file search modal
  • Clears any previous search query
  • Resets the selection to the first item
  • Automatically focuses the search input
Usage:
  1. Press Ctrl+K (Windows/Linux) or Cmd+K (Mac)
  2. Start typing to filter files
  3. Use arrow keys to navigate
  4. Press Enter to open the selected file
When a file is highlighted in the search modal, press Enter to open it.Implementation: page.tsx:420-424
if (e.key === 'Enter' && filteredFilesModal.length > 0) {
  e.preventDefault();
  setSelectedFile(filteredFilesModal[fileSearchIndex].name);
  setShowFileSearchModal(false);
}
This immediately switches to the selected file and closes the modal.

​
Theme Switching

Opens the theme selection modal with a searchable list of all themes.Implementation: page.tsx:389-395
if (e.altKey && e.key === 't') {
  e.preventDefault();
  setShowThemeModal(true);
  setThemeSearchQuery('');
  setThemeIndex(themes.findIndex(t => t.value === theme));
  setTimeout(() => themeInputRef.current?.focus(), 50);
}
What happens:
  • Opens the theme selector modal
  • Clears the search query
  • Pre-selects the currently active theme
  • Focuses the search input for immediate typing
The current theme is pre-selected, so you can immediately press ↓ to preview the next theme.
Press Enter to apply the currently highlighted theme.Implementation: page.tsx:405-409
if (e.key === 'Enter' && filteredThemes.length > 0) {
  e.preventDefault();
  setTheme(filteredThemes[themeIndex].value);
  setShowThemeModal(false);
}
The theme is applied immediately and saved to localStorage.
Press Esc to close any open modal without making changes.Implementation: page.tsx:426-429
if (e.key === 'Escape') {
  setShowThemeModal(false);
  setShowFileSearchModal(false);
}
This works for both the file search modal and theme selector.

​
Markdown Navigation

While viewing markdown content, you can use standard browser shortcuts:
  • Scroll: Space, Page Down, Page Up, Arrow keys
  • Find in page: Ctrl+F / Cmd+F (browser default)
  • Zoom: Ctrl/Cmd +, Ctrl/Cmd -, Ctrl/Cmd 0
When you click a link starting with # in the markdown content, it smoothly scrolls to that heading (page.tsx:147-152).

​
Implementation Notes

All keyboard shortcuts are implemented in a global event listener attached to the window object (page.tsx:381-434). The listener is cleaned up when the component unmounts to prevent memory leaks.

​
Cross-Platform Compatibility

File search uses (e.ctrlKey || e.metaKey) to work correctly on both:
  • Windows/Linux: Ctrl+K
  • macOS: Cmd+K

​
Focus Management

When modals open, a 50ms timeout ensures the input field is focused after the modal renders: 
setTimeout(() => fileSearchInputRef.current?.focus(), 50);
This provides a smooth user experience and allows immediate typing.

​
Event Prevention

All shortcuts call e.preventDefault() to avoid triggering browser default behaviors:
  • Ctrl+K normally opens browser’s search bar
  • Alt+T might trigger browser menu items
  • Escape might exit fullscreen mode
