How to verify on a Wired Keyboard that it has the new Lion Keys

[M&M]

I need to buy a Wired keyboard with numeric pad, but I found that there was a new version with the new key for Lion launchpad.
How can I make sure that I got the new one instead of the old version.
What's the new model number?
Is the box different?
I'm not near an apple store so I have to go to office depot and they keep very few apple items in store.
