Short cut keyboard

A shortened keyboard is a combination of Touche S which once inserted makes it possible to carry out a program, a function or an ordering of a program. The short cuts keyboard can be made up of one or several keys, one also speaks about combination of keys in the second case. To ask the Computer to carry out Instruction S, the user can have recourse to a Interpréteur of orders or to a Graphical interface. The plays also can call upon the short cuts keyboard.

Invite of order

In Line of order, only the keyboard can be used. It makes it possible to write the instructions or to carry out them using short cuts keyboards to avoid rewriting certain repetitive instructions but which remain nevertheless important such as for example erasing the screen.

Graphical interface

In a graphic Environment as propose it the majority of the operating systems recent, with windows, icons, finely S and button S, the computer can be entirely controlled with the mouse. In this case, the keyboard is then used only to write information like text and figures. But it is not the only way of proceeding, the short cuts keyboards also exist under graphical interface. By beginning the majority from the users will prefer to use the mouse because the graphical interface seems means of communication with the very intuitive and visual man. However after many hours of use, some disadvantages of this mode of piloting end up appearing: lack of precision of the mouse (especially for the mice with ball) which can cause errors, and displacements of the mouse which can constitute a light waste of time with each instruction which the user will request from the computer, which with long gives a considerable waste of time. If the short cuts keyboards initially seem not to be much more advantageous (research of the keys on the keyboard, lapse of memory of the short cuts), once controlled well they make it possible to go much more quickly and thus to increase its effectiveness. However the use alone of the keyboard is not really practical for certain activities like navigation on Internet; a good solution then remains the simultaneous use of the two peripherals of entry.

Video game

If the oldest plays and today the simple plays require of the player to use only the keyboard (like Pacman) or the mouse (like the Démineur), the majority of the recent video games on computer call upon the two peripherals of entries because they are mainly based on the interactivity. The short cuts keyboard then are often called the controls . In certain plays they make it possible to go more quickly: the strategy games (like Warcraft III, almost essential), the plays of management, simulation of life (like Sims). And for others they are essential like the sets of shootings subjective.

Use

When the short cut keyboard corresponds to a combination of key, in the majority of the cases it is not necessary to insert them exactly at the same time. For example in the environment of Windows XP and some other operating systems the combination of key ALT and F4 (noted ALT+F4 ) makes it possible to close the active window (this one to which addresses the user). It is then necessary in first to support on ALT and to maintain the key inserted then to briefly press on the key F4 . If the user maintains this combination, the window activates will then be closed then the following window will become in its active turn and will be closed almost at once. The user can thus close all his open windows (except if a program works on a file which was not recorded and which it is designed to ask the recording closing) in a short moment while the same operation can take several seconds with the mouse. The way of pressing on several keys can be parameterized in certain S.E on the level of temporization to make it possible simultaneously to facilitate the support on several keys (a combination of three keys for example can be a difficult exercise for certain users).

Average mnemotechnics

Very often, the short cuts keyboard are not selected steps chance. For certain keys, their use is very instinctive like the keys Suppr to remove, Inser to insert or Pause and Impr Écran . For the others, the programmers try to associate them with the first letter of the name which describes the action which is associated to them, to know English is then an advantage like the examples CTRL+F for Find (to seek) or CTRL+S for Save (to safeguard) shows it. In other cases, it is possible to personalize oneself its own short cuts.

To avoid having a multitude of short cuts keyboard to retain, a certain harmonization tries to be installation on the various software.
