ELECOM Mouse Assistant 'ELECOM Mouse Assistant' is software for more effectively using your mouse. Many mice are equipped with special buttons and functions, but many functions are limited to browser back & forward and horizontal scrolling in Excel. Other functions cannot be assigned to buttons on many mice. All of the buttons can be customized by using Elecom Mouse Assistant software. This software works on Windows (except RT) and Mac (Intel only). Apple Mac users can also download and install USB Overdrive, a software with which can customize a USB mouse, trackball, joystick or gamepad.
