Modifier key
In computing, a modifier key is a special key (or combination) on a computer keyboard that temporarily modifies the normal action of another key when pressed simultaneously. In general, pressing a modifier key on its own does nothing; therefore pressing any of the ⇧ Shift, Alt, or Ctrl keys alone will not usually trigger computer action. A modifier key will commonly be used in a defined sequence of key presses in conjunction with another key, triggering a specific action. These sequences are called keyboard shortcuts.
For example, in most keyboard layouts the Shift key combination ⇧ Shift+A will produce a capital letter "A" instead of the default lower-case letter "a" (unless in Caps Lock or Shift lock mode). A combination of Alt+F4 in Microsoft Windows will trigger the shortcut for closing the active window; in this instance, Alt is the modifier key. In contrast, pressing just ⇧ Shift or Alt will probably do nothing unless assigned a specific function in a particular program (for example, activating input aids or the toolbar of the active window in Windows).
User interface expert Jef Raskin coined the term "quasimode" to describe the state a computer enters into when a modifier key is pressed.
The most common are:
The (Sun) Meta key, Windows key, (Apple) Cmd key, and the analogous "Amiga key" (A) on Amiga computers, are usually handled equivalently. Under the Linux operating system, the desktop environment KDE calls this key Meta, while GNOME calls this key, neutrally, Super. This could be considered confusing, since the original space-cadet keyboard and the X Window System recognize a "Meta" modifier distinct from "Super".
The ZX Spectrum has a Symbol Shift key in addition to Caps Shift. This was used to access additional punctuation and keywords.
The MSX computer keyboard, besides Shift and Control, also included two special modifier keys, Code and Graph. In some models, as in the Brazilian Gradiente Expert, the Code and Graph keys are labelled "L Gra" and "R Gra" (Left and Right Graphics). They are used to select special graphic symbols and extended characters.
Likewise, the Commodore 64 and other Commodore computers had the Commodore key at the bottom left of the keyboard.
