Keyboard shortcut

- For Wikipedia keyboard shortcuts, see Wikipedia:Keyboard shortcuts.
A keyboard shortcut (or accelerator key, shortcut key, hot key, key binding, keybinding, key combo, etc.) is a key or set of keys that performs a predefined function. These functions can often be done via some other, more indirect mechanism, such as using a menu, typing a longer command, and/or using a pointing device. By reducing such sequences to a few keystrokes, this can often save the user time, hence "shortcut".
Sometimes, the only way to invoke a function is via some special key combination. These cases are thus technically not "shortcuts", but the terminology and notation are the same. For example, laptops often include special key combinations which adjust the screen brightness.
For shortcuts which consist of keys "pressed together", one usually first holds down the modifier key(s), then quickly presses and releases the regular (non-modifier) key, and finally releases the modifier key(s). This distinction is important, as trying to press all the keys simultaneously will frequently either miss some of the modifier keys, or cause unwanted auto-repeat.
[edit] Notation
The simplest keyboard shortcuts consist of only one key. For these, one generally just writes out the name of the key, as in the message "Press F1 for Help". The name of the key is sometimes surrounded in brackets or similar characters. For example: [F1] or <F1>. The key name may also be set off using special formatting (bold, italic, all caps, etc.)
Many shortcuts require two or more keys be pressed together. For these, the usual notation is to list the keys names separated by plus signs or hyphens. For example: "Ctrl+C", "Ctrl-C", or "[CTRL]+[C]".
Some keyboard shortcuts require keys (or sets of keys) to be pressed individually, in sequence. These are generally written with the individual keys (or sets) separated by commas or semicolons. For example "Alt+F, S" or "Alt+F; S" would mean "First press Alt and F together, then press S". Such shortcuts often represent a series of smaller shortcuts, strung together to create a larger action. To continue the "Alt+F, S" example, in many programs, this will open the "File" menu, and then invoke the "Save" function.
