Explanation:
(a) 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 a pointer on a display, which allows a smooth control of the graphical user interface of a computer.
(b) In computer displays, filmmaking, television production, and other kinetic displays, scrolling is sliding text, images or video across a monitor or display, vertically or horizontally.
(c) A mouse cursor, also known as a mouse arrow, or mouse pointer, is a graphical image that is used to activate or control certain elements in a graphical user interface. More plainly, it indicates where your mouse should perform its next action, such as opening a program, or dragging a file to another location
(d) The shift key ⇧ Shift is a modifier key on a keyboard, used to type capital letters and other alternate "upper" characters. There are typically two shift keys, on the left and right sides of the row below the home row.
(e) a key (frequently labeled Esc) found on most computer keyboards and used for any of various functions, as to interrupt or cancel the current process or running program, or to close a pop-up window.
