Description
Keyboard shortcuts are typically an alternate means for invoking one or more commands that would otherwise be accessible only through a menu, a pointing device, different levels of a user interface, or via a command console. Keyboard shortcuts generally expedite common operations by reducing input sequences to a few keystrokes, hence the term "shortcut".
Some keyboard shortcuts require the user to press a single key or a sequence of keys one after the other. Other keyboard shortcuts require pressing and holding several keys simultaneously. For simultaneous keyboard shortcuts, 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. One exception is shortcuts involving the Esc key, which almost always requires pressing and releasing the Esc key before pressing the next key.
Mnemonics are distinguishable from keyboard shortcuts. One difference between them is that the keyboard shortcuts are not localized on multi-language software but the mnemonics are generally localized to reflect the symbols and letters used in the specific locale. In most GUIs, a program's keyboard shortcuts are discoverable by browsing the program's menus - the shortcut is indicated in the menu choice. There are keyboards, commonly called Specialty Keyboards that have the shortcuts for a particular application already marked on them. These keyboards can help the users learn the shortcuts and improve their speed of using the particular applications. In certain cases, those keyboards can be created by applying shortcut stickers on a regular keyboard, which usually gives quicker access to software program features not visible otherwise. Such keyboards are often used for editing video, audio, or graphics, as well as in software training courses.

Famous quotes containing the word description:
“The next Augustan age will dawn on the other side of the Atlantic. There will, perhaps, be a Thucydides at Boston, a Xenophon at New York, and, in time, a Virgil at Mexico, and a Newton at Peru. At last, some curious traveller from Lima will visit England and give a description of the ruins of St. Paul’s, like the editions of Balbec and Palmyra.”
—Horace Walpole (1717–1797)
“To give an accurate description of what has never occurred is not merely the proper occupation of the historian, but the inalienable privilege of any man of parts and culture.”
—Oscar Wilde (1854–1900)
