1. Overview
1.1. Layout
The Multifunction Compact Keyboard supports alpha-numeric and special characters. In addition, the
keyboard supports Backspace, Enter, Arrows, Space bar, Escape, and Shift keys. The keyboard layout is
similar to a QWERTY keyboard layout available on the mobile phones. The following figure shows the top
view of the Multifunction Compact Keyboard.

keys do not have alternate characters. Character-Select key is useful to select between primary and
alternate characters. More information on Character-Select key is available in Selecting Alternate

The acceleration algorithm monitors the rate at which keyboard is being rotated. Based on the
acceleration, mouse pixel data is controlled. If keyboard is rotated fast the mouse pointer moves faster,
and vice versa. This feature is useful when cursor needs to be moved from one side of the screen to
other side.
2.2.2. Left and Right Click
In air-mouse mode, left click and right click can be performed.
•Mouse left click can be performed by taping on left side keys
•Mouse right click can be performed by taping on right side keys
Note: In Android devices, the right-click is simulated by a long touch. If the keyboard is connected to
Android devices, hold either left or right click for longer time to simulate actual right-click.
