Alt + D equivalent on a Mac?

Is there an Alt + D equivalent on a Mac. Where in Firefox it goes directly to the address bar and highlights its contents. I am growing tired of using my mouse to click the address bar.

⌘+L

Command-L on a Mac (the command key is the one with the Apple logo), Almost any Windows command which uses the control key (like copy, cut, paste) uses the command key on a Mac.
