A shortcut is a combination plus an action. The actions available:

* **Launch or focus an application**, and **toggle** one — the same key shows it
  and hides it again.
* **Open a URL.**
* **Run a command.**
* **Send a keystroke.**
* **Arrange the front window** into a slot.
* **Cycle an application's windows**, forwards or backwards.
* **Press a media key** — play/pause, next, previous, volume, mute.
* **System command** — lock, start the screen saver, show the login window,
  switch user, sleep, turn the display off, log out, restart, shut down. Three
  of those come in an asking and a non-asking pair, and three need the
  [Automation permission](/get-started/permissions#automation-for-three-system-commands).
* **Open System Settings** at one of thirty-nine panes.
* **Open menu** — a [leader menu](/features/leader-menus).
* **Run flow** — an [Action Flow](/features/flows).

## To write [#to-write]

* Each action's fields, and what an empty one falls back to
* Scoping a shortcut to particular applications
* Double tap and the Fn key as triggers
