Status Line
A status bar is a graphical control element which poses an information area typically found at the window's bottom. It can be divided into sections to group information. Its job is primarily to display information about the current state of its window, although some status bars have extra functionality. For example, many web browsers have clickable sections that pop up a display of security or privacy information. A status bar can also be text-based, primarily in console-based applications, in which case it is usually the last row in an 80x25 text mode configuration, leaving the top 24 rows for application data. Usually the status bar (called a ''status line'' in this context) displays the current state of the application, as well as helpful keyboard shortcuts. One example is the 'vi' text editor of UNIX (from the 1970s) or newer Linux systems. Status lines have been used for more than 30 years to display advisory messages in a predefined area, rather than as pop-up messages in ...

Emacs Statusline
Emacs , originally named EMACS (an acronym for "Editor MACroS"), is a family of text editors that are characterized by their extensibility. The manual for the most widely used variant, GNU Emacs, describes it as "the extensible, customizable, self-documenting, real-time display editor". Development of the first Emacs began in the mid-1970s, and work on its direct descendant, GNU Emacs, continues actively; the latest version is 28.2, released in September 2022. Emacs has over 10,000 built-in commands and its user interface allows the user to combine these commands into macro (computer science), macros to automate work. Implementations of Emacs typically feature a dialect (computing), dialect of the Lisp (programming language), Lisp programming language, allowing users and developers to write new commands and applications for the editor. Extensions have been written to, among other things, manage Dired, files, Secure Shell, remote access, Gnus, e-mail, Org-mode, outlines, EMMS (m ...

Color Space
A color space is a specific organization of colors. In combination with color profiling supported by various physical devices, it supports reproducible representations of colorwhether such representation entails an analog or a digital representation. A color space may be arbitrary, i.e. with physically realized colors assigned to a set of physical color swatches with corresponding assigned color names (including discrete numbers infor examplethe Pantone collection), or structured with mathematical rigor (as with the NCS System, Adobe RGB and sRGB). A "color space" is a useful conceptual tool for understanding the color capabilities of a particular device or digital file. When trying to reproduce color on another device, color spaces can show whether shadow/highlight detail and color saturation can be retained, and by how much either will be compromised. A "color model" is an abstract mathematical model describing the way colors can be represented as tuples of numbers (e.g. tr ...

Address Bar
In a web browser, the address bar (also location bar or URL bar) is the element that shows the current URL. The user can type a URL into it to navigate to a chosen website. In most modern browsers, non-URLs are automatically sent to a search engine. In a file browser, it serves the same purpose of navigation, but through the file-system hierarchy. Many address bars offer features like autocomplete and a list of suggestions while the address is being typed in. This auto-completion feature bases its suggestions on the browser's history. Some browsers have keyboard shortcuts to auto-complete an address. Features In addition to the URL, some address bars feature icons showing features or information about the site. For websites using a favicon (a small icon that represents the website), a small icon may be present within the address bar, a generic icon appearing if the website does not specify one. The address bar is also used to show the security status of a web page; various des ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Toolbar
The toolbar, also called a bar or standard toolbar (originally known as ribbon) is a graphical control element on which on-screen icons can be used. A toolbar often allows for quick access to functions that are commonly used in the program. Some examples of functions a toolbar might have are open file, save, and change font. Toolbars are usually distinguished from palettes by their integration into the edges of the screen or of other windows. This can result in wasted space if multiple underpopulated bars are stacked atop each other or interface inefficiency if overloaded bars are placed on small windows. Variants There are several user interface elements derived from toolbars: * An address bar, location bar or URL bar is a toolbar that mainly consists of a text box. It typically accepts URLs or file system addresses. They are found in web browsers and file managers. * A breadcrumb or breadcrumb trail allows users to keep track of their locations within a program or a file sys ...

Menu Bar
A menu bar is a graphical control element which contains drop-down menus. The menu bar's purpose is to supply a common housing for window- or application-specific menus which provide access to such functions as opening files, interacting with an application, or displaying help documentation or manuals. Menu bars are typically present in graphical user interfaces that display documents and representations of files in windows and windowing systems but menus can be used as well in command line interface programs like text editors or file managers where drop-down menu is activated with a shortcut or combination key. Implementations Through the evolution of user interfaces, the menu bar has been implemented in different ways by different user interfaces and application programs. Macintosh In the Macintosh operating systems, the menu bar is a horizontal "bar" anchored to the top of the screen. In macOS, the left side contains the Apple menu, the Application menu (its name ...

Spreadsheet
A spreadsheet is a computer application for computation, organization, analysis and storage of data in tabular form. Spreadsheets were developed as computerized analogs of paper accounting worksheets. The program operates on data entered in cells of a table. Each cell may contain either numeric or text data, or the results of formulas that automatically calculate and display a value based on the contents of other cells. The term ''spreadsheet'' may also refer to one such electronic document. Spreadsheet users can adjust any stored value and observe the effects on calculated values. This makes the spreadsheet useful for "what-if" analysis since many cases can be rapidly investigated without manual recalculation. Modern spreadsheet software can have multiple interacting sheets and can display data either as text and numerals or in graphical form. Besides performing basic arithmetic and mathematical functions, modern spreadsheets provide built-in functions for common financial a ...

Infocom
Infocom was an American software company based in Cambridge, Massachusetts, that produced numerous works of interactive fiction. They also produced a business application, a relational database called ''Cornerstone (software), Cornerstone''. Infocom was founded on June 22, 1979, by staff and students of Massachusetts Institute of Technology, and lasted as an independent company until 1986, when it was bought by Activision. Activision shut down the Infocom division in 1989, although they released some titles in the 1990s under the Infocom ''Zork'' brand. Activision abandoned the Infocom trademark in 2002. Overview Infocom games are text adventures where users direct the action by entering short strings of words to give commands when prompted. Generally the program will respond by describing the results of the action, often the contents of a room if the player has moved within the virtual world. The user reads this information, decides what to do, and enters another short serie ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Text Adventure
'' Interactive fiction, often abbreviated IF, is software simulating environments in which players use text commands to control characters and influence the environment. Works in this form can be understood as literary narratives, either in the form of interactive narratives or interactive narrations. These works can also be understood as a form of video game, either in the form of an adventure game or role-playing game. In common usage, the term refers to text adventures, a type of adventure game where the entire interface can be " text-only", however, graphical text adventures still fall under the text adventure category if the main way to interact with the game is by typing text. Some users of the term distinguish between interactive fiction, known as "Puzzle-free", that focuses on narrative, and "text adventures" that focus on puzzles. Due to their text-only nature, they sidestepped the problem of writing for widely divergent graphics architectures. This feature meant that i ...

Word Processor
A word processor (WP) is a device or computer program that provides for input, editing, formatting, and output of text, often with some additional features. Word processor (electronic device), Early word processors were stand-alone devices dedicated to the function, but current word processors are word processor programs running on general purpose computers. The functions of a word processor program fall somewhere between those of a simple text editor and a fully functioned desktop publishing program. However, the distinctions between these three have changed over time and were unclear after 2010. Background Word processors did not develop ''out'' of computer technology. Rather, they evolved from mechanical machines and only later did they merge with the computer field. The history of word processing is the story of the gradual automation of the physical aspects of writing and editing, and then to the refinement of the technology to make it available to corporations and Indi ...
