Ergonomic Keyboard Mappings for macOS

Stop moving your hand every time you need to use arrow keys:

  • Your right point finger is already on the J key
  • Press and hold a hyper key (right Command pressed with a thumb, just like a space key - in my config)
  • Use IJKL like arrow keys

Additional features:

  • Home/End navigation: Hyper + U/O moves cursor to start/end of line
  • Page navigation: Hyper + Y/H for Page Up/Down
