Mouseover. In the field of computing and web design, a mouseover, also called a hover effect, is a graphical control element. This element responds 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.
ANSI escape sequences are a standard for in-band signaling to control cursor location, color, font styling, and other options on video text terminals and terminal emulators. Certain sequences of bytes, most starting with an ASCII escape character and a bracket character, are embedded into text. The terminal interprets these sequences as ...
A mouse cursor in TUI (when implemented) is not usually the same thing as a hardware cursor, but a moving rectangle with altered background or a special glyph. Some text-based interfaces, such as that of Impulse Tracker, went to even greater lengths to provide a smoother and more graphic-looking mouse cursor. This was done by constantly re ...
The history of the graphical user interface, understood as the use of graphic icons and a pointing device to control a computer, covers a five-decade span of incremental refinements, built on some constant core principles. Several vendors have created their own windowing systems based on independent code, but with basic elements in common that ...

A typical wireless computer mouse. A computer mouse (plural mice, also mouses) [ nb 1] 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 (called a cursor) on a display, which allows a smooth control of the graphical user interface of a ...
Before the computer mouse was widespread, arrow keys were the primary way of moving a cursor on screen. Mouse keys is a feature that allows controlling a mouse cursor with arrow keys instead. A feature echoed in the Amiga whereby holding the Amiga key would allow a person to move the pointer with the cursor keys in the Workbench (operating ...
In computer graphics programming, hit-testing ( hit detection, picking, or pick correlation [1]) is the process of determining whether a user-controlled cursor (such as a mouse cursor or touch-point on a touch-screen interface) intersects a given graphical object (such as a shape, line, or curve) drawn on the screen.
