What is 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 , or by hand on a touchscreen device. The simultaneous selection of a group of items is called a multiple selection.

Context menus will usually include actions related to the objects included in the current selection - the selection provides the "context" for the menu.
