Implicit behavior

Karabiner-Elements modifies following behavior automatically without any configurations:

Share state of modifier keys with all connected keyboards

When you are using multiple keyboards, modifier keys are shared with all keyboards.

For example, pressing “shift key on keyboard1” and “space key on keyboard2” sends shift-space.

Add fn-key combinations

Karabiner adds fn-key combinations:

fn-arrow keys

Key combination Result
fn-up arrow page up
fn-down arrow page down
fn-left arrow home
fn-right arrow end
