"weird" Google Chrome feature, huge address bar pops up

I am quite puzzled by this feature since it just seems off.

When I press Ctrl + }* and I'm not in a text box.

*(basically the key below the +, left of Enter)

I get this:

A huge address bar where I can type (in this case I had typed google.com - it's not by default). The with Enter it goes to that address.

I does not have all the extra omnibar functionalities.

I am very intrigued as to why this feature is there, it seems useless (specially having Ctrl + l), it doesn't "fit" the design either.

So if anyone has any ideas as to why that is there, I would like to hear it.

Thank in advance!
