To decrease the strain and awkward posture associated with mousing, an input device that fits your hand and has programmable buttons is an excellent option. Flexibility and good fit are important features of mice and other input devices. In general, use of input devices should be minimized because they are a primary source of Repetitive Strain Injuries. Please refer to our keyboard shortcuts webpage and learn shortcuts for the operations you use frequently.

mousing hand

A neutral hand position when using the mouse is flat. The knuckles should be even to or slightly higher than the wrist. (A 5° variation is acceptable.) The fingers should rest in a waterfall position. The middle finger should be in line with the elbow. Avoid dropping your wrist. More detailed information is provided on the mouse tips webpage. (These guidelines apply to traditional mice and trackballs, not alternative devices such as the Rennaissance Mouse, RollerMouse, or touchpads.)

Rules for selecting the right input device:

  1. Your hand should fit comfortably over the device with the horizontal width and length proportional to your hand size.
  2. Devices which tilt the hand halfway between palm down and palm up are preferred.
  3. The device should minimize isolated finger and hand movements as well as force, that overwork small hand muscles.
  4. Avoid trackballs that require overuse of the thumb.

You should never "click and drag" simultaneously, especially with a trackball (i.e. never hold a button while moving the ball). By programming one of the buttons to "drag" it is possible to avoid this harmful motion which is used to select areas of data or phrases or move windows. The drag button even works in such programs as Photoshop while using the various tools like the airbrush, cloning stamp, and paintbrush which normally require large amounts of "click and drag" motion.

In order to program the input device buttons, you must first install the correct software for your mouse or trackball.

Download and install software.

If you have a Logitech mouse or trackball, please follow the instructions below. To download the latest software, go to:www.logitech.com click Support, then Downloads. Select "mice" or "trackball" and then select your model or click "Select Product by Image" and choose the image of the device that matches yours. Click the Get Software button, select your operating system, then select Set Point and follow the instructions to download and install the software on your computer.

For assistance or questions on installing or programming your Logitech input device, call Logitech technical support: (646) 454-2700.

Download and install software.

Kensington mice are all plug-and-play now, so are no longer programmable.

Trackballs are programmable by downloading TrackballWorks Software from the Software & Drivers webpage on the Kensington website. Select the version of TrackballWorks specific to your operating system and computer. Instructions for programming the trackball are also available on the Kensington website.

It is recommended that you program one of the buttons to double click and another to draglock. Also, buttons can be programmed as "keystrokes" (e.g., with one touch of a button your password appears!). IMPORTANT NOTE: You can program the right click function to be any button. If you do not use right click frequently, program this function to be a button that is not at your fingertips. This frees up the traditional "right click" button to be programmed for a repetitive or stressful task you perform frequently. Alternatively, if you don't use right click to capture images, you can eliminate programming right-click on the mouse at all and use the right-click key on the keyboard (shown below). This works for all right-click functions except image capturing.
