Keyboard shortcuts

Pressing modifier keys on their own does nothing.

Modifier keys:

Hold them down and press another key – that's when magic happens.

By pressing a combination of keys, you can do things that normally need a mouse, trackpad, or other input device.
It takes time and effort, but keyboard is twice as fast mouse will ever be.
