Windows 7 add folder to Favorites

It should be as simple as an option in a folder context menu (right-click on it) but it is not.

Method 1:
You can drag-and-drop a folder or a library to the Favorites. This is also simple but I missed it the first times I was trying.

Method 2:
1. Browse to the folder using Explorer. The full path must be fully visible and correct on the Address Bar.
3. Right-click on Favorites in the side pane.
4. Select "Add current location to Favorites" in the menu.
