How to clean under a flat keyboard?

[Manage My Cables]

So I was eating a sandwich while browsing YouTube. I'm expecting computer parts so I jumped out of my chair and raced to the door because aussie posties are ninja and in my area all seem to be allergic to doors and don't knock. When I get back to my keyboard it has a few crumbs on it so I brush them off and relies my "W" key isn't working. The keyboard is like a mac and has those flat keys that only stick a couple milometers out of the board.

 

Thanks
