When you place a bookmark in the bookmark toolbar in Safari, you can then access that bookmark using a numbered keyboard shortcut. So, reading the bookmarks from left to right, my first bookmark is YouTube and I can access it with Command (⌘)+1. I then have a few bookmark folders and the next bookmark is my online banking statement. I can check my balance any time by opening Safari and pushing Command (⌘)+2. …and so on.
This is especially useful for search bookmarks.
