A keyboard shortcut (also known as an accelerator key, shortcut key, or hotkey) is one or a set of keyboard keys that, when pressed simultaneously, perform a predefined task. Such a task could be done with the computer's pointing device, but would require the user to take his or her hands off of the keyboard, and then place them on said device. Hence, they are a shortcut in that they save the user time. In mathematics, a set can be thought of as any well-defined collection of distinct things considered as a whole. ...

Notation
A simple keyboard shortcut, requiring only one set of keys to be pressed at a time, is usually written as the names all of its component keys, separated by either a plus sign or a hyphen; for example, "Ctrl-Alt-A" or "Ctrl+Alt+A". One will usually execute such a shortcut by pressing and holding the modifier keys in each set (in this case, Ctrl and Alt), then pressing the non-modifier key as one would normally before releasing the keys. New users frequently find that they accidentally execute a keyboard command many times in rapid succession, because when told to hold keys, they make the mistake of holding all of them until key-repeat occurs. In computing, a Control key is a key, which when pressed in conjunction with another key, will perform a special operation. ...
The Alt key on a IBM PC keyboard is either of two keys located next to the Space bar, used to change the function of other pressed keys. ...
In computing, a modifier key is a special key on a computer keyboard that modifies the normal action of another key when the two are pressed in combination. ...
More complex keyboard shortcuts, which require many of these sets to be pressed in sequence, write each set in order, separated by either commas or semicolons; therefore, "Ctrl-Alt-A,B" or "Ctrl-Alt-A;B". Most keyboard shortcuts no longer require this, but they were common in earlier versions of MS-DOS and Microsoft Windows. Some examples include Ctrl+Alt+Del,Spacebar for "Lock Computer" in Windows 2000 (the initial Ctrl+Alt+Del pops up a dialogue whose default option is "Lock Computer", which the Spacebar then executes); and Alt+Spacebar,n, which minimizes a window in Microsoft Windows. Microsofts disk operating system, MS-DOS, was Microsofts implementation of DOS, which was the first popular operating system for the IBM PC, and until recently, was widely used on the PC compatible platform. ...
