Short Menu v2.x Mac OS X | 4.3 MB

Short Menu sits in your menubar, waiting for you to shorten an URL. It supports 20 different services and is very easy to use. Simply click on Short Menu's menubar icon to open it. It automatically takes the URL from your clipboard. You only have to press one button, then Short Menu will shorten your URL and automatically copy the short URL for you. After shortening an URL, Short Menu saves both URLs in the history and sends a notification to you. These notifications are optional and you can configure them in the preferences.

But there are more and faster ways to shorten an URL with Short Menu. A feature called Quick Short makes it possible to shorten an URL with a shortcut. Just press the shortcut you entered, and Short Menu takes the URL from your clipboard, shortens it and automatically copies the short URL for you. If you want to use Short Menu even faster, you'll love the feature Auto Short. If it's activated, it watches your clipboard and waits for you copying an URL. When it detects an URL, it shortens it and automatically copies the short URL for you. If you don't want to let Short Menu watch your clipboard or to use shortcuts, you can right-click Short Menu's menubar icon to shorten the URL from your clipboard. While shortening an URL in background with these features, Short Menu's menubar icon will animate, so that you see that it works.

To use Droplr and CloudApp you have to login to your own account in Short Menu's preferences. You can also use your own bit.ly account for the services bit.ly and j.mp, but that's optional. If you have multiple accounts of a service, you can login to all and switch between your accounts. You also don't have to use Short Menu's standard services. You can configure as many custom services as you want in Short Menu's preferences.
