The scroll lock key was meant to lock all scrolling techniques, and is a remnant from the original IBM PC keyboard, though it is not used by most modern-day software. In the original design, scroll lock was intended to modify the behavior of the arrow keys. When the scroll lock mode was on, the arrow keys would scroll the contents of a text window instead of moving the cursor. In this usage, scroll lock is a modifier key like Alt and Shift(which modify the function of other keys) and, more specifically, a toggling lock key like Num Lock or Caps Lock, which have a state that persists after the key is released. 4, record 3, English, - Scroll%20Lock%20key

Scroll lock key ... Microsoft Excel is a good example of a software program that uses this key. If scroll lock is enabled on the keyboard when you press any of the arrow keys the screen will move in that direction but the selected cell will not change. However, if scroll lock is not enabled you will be able to navigate through each of the cells using the arrow keys. 3, record 3, English, - Scroll%20Lock%20key

La touche Arrêt Défilement affecte les touches de contrôle du curseur sur le pavé numérique ou, dans le cas du clavier étendu, les touches flèches situées entre le pavé numérique et le clavier principal. Selon l'état de la touche Arrêt Défilement, le fonctionnement des touches curseur dépend de l'application; dans un traitement de texte, par exemple, les touches curseur feront défiler le document autour du curseur si Arrêt Défilement est enclenchée, alors c'est le curseur qui se déplacera si Arrêt Défilement n'est pas enclenchée. 4, record 3, French, - touche%20Arr%C3%AAt%20D%C3%A9filement

Le but de notre expérience est de mesurer une accélération angulaire. Pour ce faire, un interféromètre à effet Sagnac sera utilisé. Il s'agit d'un dispositif expérimental permettant l'analyse d'une figure d'interférence produite par un faisceau laser. Le faisceau est coupé en deux par un miroir semi-transparent et, à la différence de l'interféromètre de Michelson, le trajet suivi par les rayons est circulaire. Chaque rayon tourne dans un sens différent et donc, selon l'état de rotation du système, le déphasage entre les rayons est sensible à l'accélération angulaire du dispositif. Quand l'interféromètre de Michelson permet de mesurer une accélération linéaire, l'interféromètre à effet Sagnac permet de mesurer une accélération angulaire. Le principe de cet effet correspond à un effet Doppler rotationnel. Il a été découvert par Sagnac en 1913.
