The modern computer mouse has evolved from a primitive joystick-type device used to navigate around old radios and computers to a current product that allows one hand to control a computer's pointer and execute different commands based on pressing different buttons on the mouse. Some sophisticated mouses include customizable buttons for even more options.

Below is a high-end gaming/design mouse with multiple controls as illustrated below.

The four customizable side buttons, controlled by the thumb on the left and ring finger on the right, can be assigned commands in the software that comes with the mouse, meaning its function is easily tuned to the user's desire. Most mouses similar to this one are also compatible with a wide variety of laptops and desktop computers ranging from PCs to Macs to Chromebooks.
