NO NUMBER PAD AND EXTREMELY LOW PROFILE AIDS COMFORT. The numeric keys on the right side of a full size keyboard makes the mouse sit too far away and your right arm too extended. Eliminating the numeric keys not only saves space, but your mouse can get closer so your arm is more relaxed. The back edge is not tilted up so the entire keyboard is fully flat to eliminate the need to strain your hands upward. The key tops are only 1 cm/0.4″ off the top of the desk to further reduce wrist strain. | EXTREMELY LOW PROFILE AIDS COMFORT.

Hotkeys provide one touch operation for Undo, Cut, Copy, Paste, Web, E-mail, Computer, Mute, Volume Down, Volume Up, Sleep, and Turn Off. All functions are each accessible with one key, unlike other compact keyboards which require also pressing a Fn key simultaneously. | HIGH QUALITY SCISSOR KEYS. Precision scissor keys provide crisp action and good feedback, unlike some compact keyboards which use wobbly membrane keys that feel mushy. | WIRED PLUG AND PLAY WITHOUT DRIVER. All the hotkeys work without a driver in Windows XP or newer. The hotkeys do not work with Mac OS but all other keys work and Mac functions are printed on some keys.
