everything works. Even those small circle buttons at the side of the trackpad. All of the buttons works!!! I pressed the internet "e" icon on the keyboard and my laptop automatically opened the browser page. Great quality, great price, great piece of a product, absolutely must have if you want a wireless handheld keyboard. I bought this keyboard to work with the mini pc 'VIA 8850" that i also purchased from lightinthebox. I haven't tried it yet with the mini pc as the mini pc needed to be charged for 6 hours before use. Will edit my post when i get the chance to try this keyboard with the mini pc. Thank you lightinthebox!!!!
