System actions

System actions are things you do to the machine rather than to a file. Each one is searchable and each one can take a global shortcut.

They live in their own System Actions section, and are configured in Settings → System Actions.

The full list

Session — Lock Screen · Sleep · Sleep Displays · Restart · Shut Down · Log Out · Show Screen Saver

Media — Play / Pause · Next Track · Previous Track

Volume — Toggle Mute · Turn Volume Up · Turn Volume Down · Set Volume… · Set Volume to 0% / 25% / 50% / 75% / 100%

Desktop — Show Desktop · Toggle System Appearance · Toggle Stage Manager · Hide All Apps Except Frontmost · Unhide All Hidden Apps · Quit All Applications · Dismiss Notifications

Files — Open Trash · Empty Trash · Eject All Disks · Toggle Hidden Files

Hardware — Toggle Bluetooth

Confirmation

Five actions ask first, because getting them by accident is expensive:

Restart · Shut Down · Log Out · Empty Trash · Quit All Applications

↵ runs, ⎋ cancels. Each confirmation carries that action's own icon, so you can tell at a glance what you are about to do.

The gate applies to the global shortcut too. There is no way to bypass it, and holding a shortcut down cannot stack up dialogs.

What you see afterwards

Actions with no visible effect report the state they landed in — Trash Emptied, Hidden Files Shown, Dark Appearance, Bluetooth Off, 3 Disks Ejected.

A green check means something changed. A neutral dot means there was nothing to do: Trash Is Already Empty is an outcome, not a failure, and the same goes for Eject All Disks, Dismiss Notifications and Unhide All Apps.

Volume

Volume Up and Down walk a 5% grid — from 37%, up lands on 40% and down on 35%.

Tinycast draws its own volume HUD, because macOS only shows one for real media keys. It prints the level as text, shows Muted rather than 0%, and dismisses after 1.6 seconds. Arrow keys walk the same 5% grid; clicking the track jumps straight to a level.

Toggle System Appearance

This changes macOS itself, not just Tinycast. Tinycast follows along only while its own theme is set to System.

Permissions

Automation, Accessibility and Bluetooth are requested at first use of the specific action that needs them, never up front. If you deny one, you get an alert with a link to the right System Settings pane rather than a silent no-op.

Settings

Settings → System Actions is a list with a Show in launcher master toggle, and per action a visibility checkbox, a shortcut recorder and an alias field. There is a filter field at the top, which you will want with 31 rows.
