 The Alt key on a modern Windows keyboard The Alt key on an IBM PC keyboard is the key located immediately to either side of the Space bar, 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 almost identical 'Alt Gr' key to the right of the space bar. ImageMetadata File history File links Ctl_wndws_alt. ...
