A method for operating an input device and keyboard for a computer. The input device has controls including an ergonomically shaped input button that receives commands from a user and transmits the commands to the computer via a communication link. Users operate the input device by engaging the lower surfaces of their fingers with lower portions of the input button and engaging side surfaces of their fingers with side portions of the input button. Where the input button is curved as it extends away from the users, the users may also curl their fingers to fit the curve of the input button. The users may then depress the input button vertically downward in one embodiment, or at an acute angle to the vertical in another embodiment, or horizontally in yet another embodiment. In still a further embodiment, the input device may be housed within an opening in the keyboard and the users may detach the input device from the keyboard by removing it from the opening and operate the input device when it is either attached to or detached from the keyboard. In yet another embodiment, left and right input devices are removably attached to the keyboard and the users may operate the left input device with their left hands and the right input device with their right hands.
