4. Global Keyboard Shortcuts (Automator)

For quick access to Hush from anywhere on your system, you can create a global keyboard shortcut using macOS Automator:

Setup Instructions

  1. Open Automator → Create new Quick Action
  2. Set workflow to receive: "no input" in "any application"
  3. Add action: Search for "Launch Application" and drag it to the workflow
  4. Select Hush from the application dropdown
  5. Save the Quick Action (e.g., "Launch Hush")
  6. System PreferencesKeyboardShortcutsServices
  7. Find your Quick Action and assign a keyboard shortcut (e.g., ⌘⌃H)

⚠️ Important Shortcut Considerations

  • Check for conflicts: Verify your chosen shortcut isn't already used by other apps or system functions
  • Test thoroughly: Some shortcuts may fail if they conflict with browser extensions, other applications, or system shortcuts
  • Recommended shortcuts: ⌘⌃H, ⌘⌃Space, ⌘⌃T (check availability first)
  • Avoid common shortcuts: Don't use shortcuts already assigned to Mission Control, Spotlight, or frequently used apps

Troubleshooting Global Shortcuts

  • If the shortcut doesn't work, check System PreferencesKeyboardShortcuts for conflicts
  • Some applications (especially browsers) may override global shortcuts
  • Try alternative key combinations if your first choice doesn't work consistently
  • Consider using function keys (F1-F12) combined with modifiers for more reliable shortcuts
