Safari Feature, or Bug?

One of my most common usages of Safari is to open a new tab and then type in an address. I do this a lot to open up a few sites and shift over to whatever one I started first. The drawback to this is that you shift focus to the new blank tab whenever you open a new one and type in address. This morning I found a new way:

1. it Command L to type in an address.
2. Type in the new address.
3. Instead of hitting Return to go to the new address, hit Command Return to open up a new tab in the background to the new address

Sweet!

This probably only works if you (a.) have tabbed browsing enabled, (b.) have "open new tabs in background" or some-such enabled.
