About K400 Plus
Wireless Touch Keyboard K400 Plus is a full size keyboard layout and touchpad in a compact size.
Incurve keys are ideal for touch typists and the soft key stroke makes this a quiet keyboard.
The full size touchpad gives you the familiar scroll and navigation gestures. With the left- and right-click buttons below the touchpad and the volume control buttons above, control is at your fingertips.
For two-hand control, typically used by those who like to use their thumbs to navigate, a left mouse-click button is located on the upper left side of the keyboard—navigate with your right hand, select with your left.
