If you enjoy the convenience of the Dock, you can make it even more useful by adding items to it you use regularly. Here, for example, you’ll find two ways to add one or more applications to your Dock.
Let’s say you’re currently using Keynote ’08, your favorite presentation software, and would like to keep it in the Dock at all times. Right-click on its icon in the Dock, and select Keep in Dock from the contextual menu that appears.
Or try this option. Open the Applications folder, grab Text Edit, and drag it to the Dock. Next time you want to use Text Edit, just click its icon in the Dock.
You can use this method to add multiple applications just as easily. In that open Applications folder, choose Calculator and Dictionary, two handy utilities, and drag both into the Dock.
