Notes

  • On macOS, use Cmd instead of Ctrl and (Option) instead of Alt
  • Most navigation can be done using either arrow keys or vim-style H/J/K/L keys
  • When TTS is active, Space toggles play/pause instead of navigating to the next page
  • The sidebar can be quickly toggled with a single key (S) for more reading space
  • Feel free to reach out if you have suggestions for additional shortcuts or improvements!
