For most average computer users, the most passive mouse button is usually the middle one. The middle button is usually used to scroll documents or web pages, and almost for nothing else. In case you are wondering if you can put the middle mouse button to a good use, you might want to try MouseExtender.

MouseExtender is a small program that ran on the system tray and it will display a nice menu that contains shortcuts to file, program, folder and URL by clicking the middle mouse button. You can group shortcuts which belong in same category using tabs.

By default, MouseExtender will override other programs’ function that uses the middle mouse button. For example, clicking the middle button on webpage in a web browser will gives you the ability to scroll the webpage using the cursor, and when you’re running MouseExtender, it will bypass this function and displays shortcuts. However, MouseExtender allows you to exclude programs from displaying the shortcuts and let the program uses its default middle click function.

MouseExtender is free and open source. MouseExtender is available for Windows operating system and requires Microsoft .NET Framework 3.5 SP1. MouseExtender doesn’t require installation so you can run it from your portable drive.
