Right shift key minimizes screen

Maybe this is a dumb question but is there any way to disable the special effect of pressing the 'Right Shift Key' on my macbook air 13? When just that key is pressed, by itself or in combination with any other key(s), it minimizes the window I'm working on, allowing me to partially see the rest of the desktop, and not allowing me to do anything in that window until I press it again to re-maximize the window. I'd prefer to disable this "feature" so that I can use either shift key when typing ('Left Shift Key' just operates as a normal shift key).

Much appreciated!

Go to the Keyboard Shortcuts tab in the Keyboard preference and hit the Restore Defaults button.
That should do it.

Nope, doesn't fix it. Thanks for trying though.

As far as I know it's not a "feature" but a wrong setup. My right shift key on my new MBP 13" does nothing but change the case of the letter I use it with. Something is wrong in your key modifiers. Somehow it got changed. So resetting the keyboard keymaps should fix it.
