The Alt key (pronounced /ˈɔːlt/) on a computer keyboard is used to change (alternate) the function of other pressed keys. Thus, the Alt key is a modifier key, used in a similar fashion to the Shift key. For example, simply pressing "A" will type the letter a, but if you hold down either Alt key while pressing A, the computer will perform an Alt+A function, which varies from program to program. In non-US keyboard layouts, rather than a second Alt key, there is an 'Alt Gr' key to the right of the space bar. The key is located immediately to either side of the Space bar. Some keyboard layouts treat both Alt keys on the keyboard as the same key, while others do not.
