App: Switcheroo - Fast App Switcher
Developer: Jacob Schwartz
Genres: Dienst­programme, Produktivität

Switcheroo lets you launch and switch between your favorite applications with speed and simplicity. With just a single keystroke, you can immediately switch to a specified running application, or launch one that is not running. Before long Switcheroo will be muscle memory and your friends and coworkers will envy your ultrafast app switching.

Here's how to use Switcheroo:
1. Hold the right command key and press the application's shortcut key
2. That's it!

The setup instructions are simple:
1. First, launch an application by double-clicking the icon or using Spotlight
2. Then hold the right command key (the looped square to the right of your spacebar) and click the app you just launched in the Switcheroo Hints window.
3. Pick a letter or number to assign to this application and, while still holding the right command key, press that key. For example, 'S' for Safari.
4. Repeat with other applications. You can replace shortcut keys, or clear them by pressing Delete.

You're done! Now you can launch that application by simply holding the right command key and pressing the shortcut key you chose before. Note that your left command key still works like normal.

New: You can now toggle the Trigger Key between the right command key and right option keys via the Options menu.

Release notes:
Even. Faster. Switching.
