GroupCtrl

Instant app switching with shared hotkeys

Download

Features

• Hotkey sharing: Create an app group with multiple related apps and assign a single hotkey to it. Hit once to switch to the most recent app, hit again to cycle to next running.
• Fixed target: Optionally select one app per group to always open first. If not running, it will be launched.
• Text config: Easy to manually edit and version-control, if you're so inclined.

Tips

• Add GroupCtrl to Open at Login in System Settings
• Use Hyperkey or Karabiner to map Caps Lock to Cmd+Opt+Control
• Config path is ~/.config/groupctrl/config.yaml

Useful macOS shortcuts

• Cmd+Opt+D to hide Dock
• Cmd+Backtick to switch between windows of an app
• F11 to show desktop

Alternatives

• rcmd – Similar functionality, but no practical hotkey sharing
• FlashSpace – Workspace manager with app hiding
• AeroSpace – Tiling window manager

I've used all three extensively but was never quite satisfied. I wanted to build something that combines the simplicity of rcmd with the flexibility of FlashSpace and the consistency of AeroSpace.
