Selection (user interface) in the context of Simultaneous editing

⭐ Core Definition: Selection (user interface)

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.

Selections are enacted through combinations of key presses on a keyboard, with a precision pointing device (mouse or touchpad and cursor, stylus), or by hand on a touchscreen device. The simultaneous selection of a group of items (either a subset of elements in a list, or discontinuous regions in a text) is called a multiple selection.

👉 Selection (user interface) in the context of Simultaneous editing

In human–computer interaction, simultaneous editing is an end-user development technique allowing a single user to make multiple simultaneous edits of text in a multiple selection at once through direct manipulation.

Multiple selections and cursors are typically created by using a keyboard shortcut to select repeated instances of the same text or text fragments surrounded by the same delimiters, by using a search feature to select all instances of a search term, by selecting the same column in multiple lines, or by selecting text or cursor positions with a mouse. The Lapis experimental web browser and text editor is also able to infer selections based on concept learning from positive and negative examples given by the user during a process known as selection guessing.

Selection (user interface) in the context of Copy and paste

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.

The command names are a (skeuomorphic) interface metaphor based on the physical procedure used in manuscript print editing to create a page layout, like with paper.The commands were pioneered into computing by Xerox PARC in 1974, popularized by Apple Computer in the 1983 Lisa workstation and the 1984 Macintosh computer, and in a few home computer applications such as the 1984 word processor Cut & Paste.
