<span class="mw-page-title-main">Computer mouse</span> Pointing device used to control a computer

A computer mouse is a hand-held pointing device that detects two-dimensional motion relative to a surface. This motion is typically translated into the motion of the pointer on a display, which allows a smooth control of the graphical user interface of a computer.

<span class="mw-page-title-main">Graphical user interface</span> User interface allowing interaction through graphical icons and visual indicators

A graphical user interface, or GUI, is a form of user interface that allows users to interact with electronic devices through graphical icons and visual indicators such as secondary notation. In many applications, GUIs are used instead of text-based UIs, which are based on typed command labels or text navigation. GUIs were introduced in reaction to the perceived steep learning curve of command-line interfaces (CLIs), which require commands to be typed on a computer keyboard.

The keyboard for IBM PC-compatible computers is standardized. However, during the more than 30 years of PC architecture being frequently updated, many keyboard layout variations have been developed.

A pointing device is a human interface device that allows a user to input spatial data to a computer. Graphical user interfaces (GUI) and CAD systems allow the user to control and provide data to the computer using physical gestures by moving a hand-held mouse or similar device across the surface of the physical desktop and activating switches on the mouse. Movements of the pointing device are echoed on the screen by movements of the pointer and other visual changes. Common gestures are point and click and drag and drop.

<span class="mw-page-title-main">Text editor</span> Computer software used to edit plain text documents

A text editor is a type of computer program that edits plain text. An example of such program is "notepad" software. Text editors are provided with operating systems and software development packages, and can be used to change files such as configuration files, documentation files and programming language source code.

Cut, copy, and paste are essential commands of modern human–computer interaction and user interface design. They offer an interprocess communication technique for transferring data through a computer's user interface. The cut command removes the selected data from its original position, and the copy command creates a duplicate; in both cases the selected data is kept in temporary storage called the clipboard. Clipboard data is later inserted wherever a paste command is issued. The data remains available to any application supporting the feature, thus allowing easy data transfer between applications.

<span class="mw-page-title-main">Computer terminal</span> Computer input/output device for users

A computer terminal is an electronic or electromechanical hardware device that can be used for entering data into, and transcribing data from, a computer or a computing system. Most early computers only had a front panel to input or display bits and had to be connected to a terminal to print or input text through a keyboard. Teleprinters were used as early-day hard-copy terminals and predated the use of a computer screen by decades. The computer would typically transmit a line of data which would be printed on paper, and accept a line of data from a keyboard over a serial or other interface. Starting in the mid-1970s with microcomputers such as the Sphere 1, Sol-20, and Apple I, display circuitry and keyboards began to be integrated into personal and workstation computer systems, with the computer handling character generation and outputting to a CRT display such as a computer monitor or, sometimes, a consumer TV, but most larger computers continued to require terminals.

In computing, an icon is a pictogram or ideogram displayed on a computer screen in order to help the user navigate a computer system. The icon itself is a quickly comprehensible symbol of a software tool, function, or a data file, accessible on the system and is more like a traffic sign than a detailed illustration of the actual entity it represents. It can serve as an electronic hyperlink or file shortcut to access the program or data. The user can activate an icon using a mouse, pointer, finger, or voice commands. Their placement on the screen, also in relation to other icons, may provide further information to the user about their usage. In activating an icon, the user can move directly into and out of the identified function without knowing anything further about the location or requirements of the file or code.

A gap buffer in computer science is a dynamic array that allows efficient insertion and deletion operations clustered near the same location. Gap buffers are especially common in text editors, where most changes to the text occur at or near the current location of the cursor. The text is stored in a large buffer in two contiguous segments, with a gap between them for inserting new text. Moving the cursor involves copying text from one side of the gap to the other. Insertion adds new text at the end of the first segment; deletion deletes it.

In user interface design, a menu is a list of options presented to the user.

Point and click are one of the actions of a computer user moving a pointer to a certain location on a screen (pointing) and then pressing a button on a mouse or other pointing device (click). An example of point and click is in hypermedia, where users click on hyperlinks to navigate from document to document. User interfaces, for example graphical user interfaces, are sometimes described as "point-and-click interfaces", often to suggest that they are very easy to use, requiring that the user simply point to indicate their wishes. Describing software this way implies that the interface can be controlled solely through a pointing device with little or no input from the keyboard, as with many graphical user interfaces.

In a computing graphical user interface (GUI), a component has focus when it is selected to receive input from the user by an event such as a mouse button click or keypress. Moving the focus away from a specific user interface element is known as a blur event in relation to this element. Typically, the focus is withdrawn from an element by giving another element the focus. This means that focus and blur events are virtually simultaneous in relation to different user interface elements, one that becomes focused and one that is "blurred".

<span class="mw-page-title-main">Text-based user interface</span> Type of interface based on outputting to or controlling a text display

In computing, text-based user interfaces (TUI), is a retronym describing a type of user interface (UI) common as an early form of human–computer interaction, before the advent of bitmapped displays and modern conventional graphical user interfaces (GUIs). Like modern GUIs, they can use the entire screen area and may accept mouse and other inputs. They may also use color and often structure the display using box-drawing characters such as ┌ and ╣. The modern context of use is usually a terminal emulator.

<span class="mw-page-title-main">Mouseover</span> User interface element

In the field of computing and web design, a mouseover, is an event occuring when the user moves the cursor over a specified point on a computer monitor using a computer mouse. Also called a hover effect, mouseovers are graphical controls that respond when a user moves their mouse pointer over a designated area. This area can be a button, image, or hyperlink. This simple action can trigger different responses. The element's color or appearance can change. Additional information or interactive content can be displayed. The mouseover effect is an essential part of user interaction. It adds layers of interactivity and responsiveness to websites and applications.

In human–computer interaction, a cursor is an indicator used to show the current position on a computer monitor or other display device that will respond to input.

ND-NOTIS was a office automation suite by Norsk Data introduced in the early 80s, running on the SINTRAN III platform on both ND-100 and ND-500 architectures. It was also available on Microsoft Windows running in networks of Norsk Data servers.

<span class="mw-page-title-main">Snippet (programming)</span> Small region of re-usable source code, machine code, or text

Snippet is a programming term for a small region of re-usable source code, machine code, or text. Ordinarily, these are formally defined operative units to incorporate into larger programming modules. Snippet management is a feature of some text editors, program source code editors, IDEs, and related software. It allows the user to avoid repetitive typing in the course of routine edit operations.

In computing and user interface engineering, a selection is a list of items on which user operations will take place. The user typically adds items to the list manually, although the computer may create a selection automatically.
