Operating the Media Center applications is easily accomplished. The hotkeys for standby, TV function either intuitively how to or are quickly set up. Aaaber: I just missing a few keys: The multimedia keys share the buttons with the function keys. For a multimedia keyboard, it is also logical that the multimedia keys are important, so you get the F key by holding the Fn key. But now I'm used to it with Alt-F4 to close windows and programs. So I have already several times my computer sent to standby, because Alt-F4 namely not caught the F- but the Standby button (without Fn). Keys Pos1 and end there is not, therefore is serious work in a word processing difficult.
Maybe it is also due to my fingers, but the 10-finger tap I often meet also not interruptible touchpad, which to my mind even realtiv "nervous" reacted promptly and write somewhere else. Double double via tip fails mostly because even with a short tip making the mouse pointer already again in any direction on the socks.
If there was a button that permanently switches between F-function and multimedia, and I by typing Alt-Fn-F4 not have to break your fingers, the touchpad would be less nervous and would at least have the Pos1- and the end key because (a context menu button I've already missed), it would certainly be my favorite multimedia keyboard. So I remain in the K400, whose much too small touchpad works precisely and at least in which all keys are present.
