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 elements in a list, or discontinuous regions in a text) 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. == Types of selections == * Text selection is associated with the cut, copy and paste operations and done with a cursor, caret navigation or touch. * Image editing applications can feature specialized graphical tools for the selection and modification of areas and shapes or to interact with colours, such as the magic wand selection tool, the lasso selection tool, the marquee selection (bounding box), or the color picker. The border of a selected area in an image is often animated with the marching ants effect to help the user to distinguish the selection border from the image background. * Video editing programs may utilise dynamic controls and advanced digital effects on the selected region. * Files and other interface components can be selected and used with the advent of GUIs. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Selection (user interface)」の詳細全文を読む スポンサード リンク
