You have used the Sidebar a number of times already. Here are a couple of extra tips, as well as a press-and-drag practice.
Remove items from the Sidebar
You can remove any item from the Sidebar. This doesn't destroy anything! You are only removing an icon that represents the original file—you are not deleting any original files at all.
Exercise: Delete an item from the Sidebar.
- To remove any item from the Sidebar, hold down the Command key and drag the item to the Desktop. It disappears in a puff of smoke, as shown below.
Add items to the Sidebar
You can add other items to the Sidebar. You might want to add files or folders that you use the most often. You might want to put a current project folder here or, if your Dock is getting over-crowded, a favorite application.
- Find the item that you want to add to your Sidebar.
- Drag that item's icon to any position under the "Favorites" heading (you aren't allowed to put it anywhere else).
