    Looking for a windows 8 keyboard? BUY THIS NOW
    If you're looking for a keyboard specifically for windows 8, look no further. I'm running windows 8 on a desktop. it's a gaming pc hooked up to a 55 inch flat screen, with a 15ft HDMI cord. Most of my game I use a wireless xbox 360 controller for with steam's new big picture mode. After upgrading to windows 8, I noticed right away keyboard shortcuts and gestures are the way to move around inside the OS.That said I already have a keyboard but my cable was to short, I have a wireless mouse but using a mouse to get around windows 8 just does not make any sense. So it brought me to the decision that I needed a wireless keyboard and some way of using touch based gestures. But there was no way in heck I was going to shell out the money for a touchscreen monitor ,that I'm never going to use, and tablet apps so far just aren't cutting it!When I first saw this keyboard on amazon I was kind of turned off by it, because I already have pretty much the same keyboard for my google tv box, and that ones not very nice to type on at all and over all kind of cheap.But I can say with confidence, this is a step far above the one that came with my revue. The keys feel much more like a full size mechanical keyboard, and less of a laptop keyboard. The hot keys on top allow you to : show desktop, switch apps, search, share, open devices, open settings in the charm bar, media controls (<< II> >>), mute, volume up and down. all of these functions happen by default if you want to use the normal function keys you have to hit the function button. This is fantastic, no more hitting two buttons just to control media or use CRITICAL hot keys in windows 8!Touch based gestures include: pinch to zoom, swipe left edge to center to change apps, swipe from right edge to open the charms bar, two finger scrolling (both vertically and horizontal), two finger tap for right click.range is fantastic, with my other keyboard I can attest to the one year battery life, and I'm sure this will last just as long.Overall if you just want a wireless keyboard, there's probably some better choices out there. But if you want to make windows 8 your B**ch, this IS the board your looking for! Oh and the top three hot keys in the picture on here are incorrect, there's a key dedicated to opening xbox music, a home button, and a lock pc button. and they've also added in a PC power button, but so far I can't get that to work, I'm sure there's a setting somewhere IDK about.

    Reviewed in Japan on June 3, 2020
    タイトルの通り。届いた商品パッケージには確かにK400と書かれているがキー配列がWEBの商品写真と異なる。
    実際に届いたK400のパッケージのキー配列はK400rと同じ様だ。
    具体的にはF1-F12キーに別のキーが割り当てられている、上部のホットキーの割り当てキーがWEBの商品写真と異なる。
    写真を追加したので詳しくはそちらを参照して欲しい。

    少し調べたところ、どうやらK400には仕様の違う初期型と後期型がある様だ。
    初期型がWEBの商品写真のキー配列。F1-F12キーがそのまま使える。
    後期型がK400rのキー配列。F1-F12キーはFNキーと当時押しが必要。
    F1-F12キーがFNキーと同時押しする必要があるK400plusやK400rが嫌でこの商品が欲しい場合は注意。
    私はこの点を期待して買ったのに意味が無く返品申請した。
    買う前に販売業者にキー配列を問い合わせする事をオススメする。
