COMPUTING On a computer, scrolling may be performed by software running on a computer's CPU , or it may be done by performing some operation on a dedicated 2D Computer Graphics chip. In a WIMP -style Graphical User Interface , scrolling is done with the help of a Scrollbar or using keyboard shortcuts, often the Arrow Key s. Scrolling is often a key feature in Text User Interface s and Command Line Interface s, though some older Computer Terminal s used a paging mode instead, akin to flipping through a series of pages in a book. Modern Computer Mice may also have a Scroll Wheel . If any content is too wide to fit on a display, horizontal scrolling is often required to view all of it. This is often considered impractical and annoying, as the user must scroll back and forth in two Dimension s, instead of just up and down. Such a problem is very common on certain Website s; one exception to this rule is Spreadsheet s, as they are arranged in a fashion that makes this less of a problem. On the other hand, vertical scrolling is very common, as it only requires movement in a single dimension. TELEVISION Scrolling is commonly used to display the credits at the end of television shows. Scrolling is also used in Television News when a News Ticker is employed, scrolling news stories horizontally across the bottom of the screen. VIDEO GAMES In Computer And Video Games , scrolling of a playing field allows the player to control an object in a large contiguous area. '' Super Bug '' pioneered this method. Parallax Scroll ing, which was first featured in '' Moon Patrol '', involves several Semi-transparent layers, which scroll on top of each other at varying rates in order to give the illusion of depth. A previously much used alternative to video game scrolling is the Flip-screen method. DEMOS Scrolling texts, also referred to as ''scrolltexts'' or ''scrollers'', were an integral feature of the majority of the Demos written for Home Computer s in the 1980's . They were particularly important in Crack Intro s programmed by Software Cracker s, where they were used to convey messages between groups involved in the activity. Many scrollers were plain horizontal scrollers, but Demo Coders also paid a lot of attention in finding new and different types of scrolling. The characters could, for example, continuously alter their shape, take unusual flying paths or incorporate color effects such as Raster Bar s. |
