A conventional right-hand keyboard has navigation and numeric keys occupying valuable space on the right side. When the character keys are centered in front of you in a proper typing position, you have to stretch out your arm to reach the mouse. Some users compensate for this problem by offsetting the keyboard to the left, which makes the typing position less comfortable. The Evoluent keyboard's numeric keypad is uniquely on the left side to let you put the mouse much closer. Your reach to the mouse is greatly reduced for a more relaxed arm position. A conventional keyboard forces you to frequently move your right hand from the mouse to the keyboard to press Enter, Del, Page Up, Page Down, Backspace, Home and End.
