Redcast System actions
31 built-in actions for your Mac, like lock, sleep, volume, Bluetooth and the Trash.
System actions control your Mac itself, like locking the screen or emptying the Trash. You can search for each one, and each one can have a global shortcut.
They have their own System Actions section in the launcher and their own pane in Settings → System Actions.

Confirmation
Five actions ask for confirmation first, because running them by accident would be costly:
Restart · Shut Down · Log Out · Empty Trash · Quit All Applications
return runs the action and esc cancels. Each dialog shows the action's icon, so you can see what you're about to do. Quit All Applications also tells you how many apps it will quit.
Empty Trash follows your Finder setting. It only asks while Show warning before emptying the Trash is on in Finder ▸ Settings ▸ Advanced. If you turn that off, Empty Trash runs without a dialog.
The same confirmation appears when you use a shortcut. You can't skip it, and holding down a shortcut never opens more than one dialog.
What you see afterward
Actions without a visible effect show a short message with the result, like Trash Emptied,
Hidden Files Shown, Dark Appearance, Bluetooth Off or 3 Disks Ejected.
A green check means something changed. A plain dot means there was nothing to do. For example,
Trash Is Already Empty isn't an error, and neither are similar messages from Eject All Disks,
Dismiss Notifications and Unhide All Hidden Apps.
A few details
Volume. Turn Volume Up and Turn Volume Down move in 5% steps: from 37%, up goes to 40% and
down goes to 35%. Redcast shows its own volume indicator, because macOS only shows one for the
hardware media keys. It shows the level as a number, shows Muted instead of 0%, and fades out
after 1.6 seconds.
Eject All Disks ejects external and removable drives, including a hard drive connected through a dock. It never ejects internal or network volumes.
When you run Hide All Apps Except Frontmost or Quit All Applications from a shortcut with the palette closed, they act on the app that's actually in front. Quit All Applications leaves Finder and Redcast running and asks apps to quit normally, so apps with unsaved work still ask you to save.
Toggle System Appearance changes the appearance of macOS itself, not only Redcast. Redcast follows the change only while its own theme is set to System.
Permissions
Some actions need Automation, Accessibility or Bluetooth access. Redcast asks the first time you run an action that needs it, never in advance. If you decline, you see a message with a link to the right System Settings pane, so the action never fails silently.
Settings
Settings → System Actions has Enable System Actions at the top and a row for each action, with a launcher checkbox, a shortcut recorder and an alias field. Use the filter field at the top to find an action among the 31 rows.
Turning off Enable System Actions removes every action from search and turns off their shortcuts. Clearing a single row's checkbox only hides that action from search, which is the same as pressing ⇧⌘H on it in the launcher.
