A hand-held input device that is moved about on a flat surface to direct the cursor on a computer screen. It also has buttons for activating computer functions. The underside of a mechanical mouse contains a rubber-coated ball that rotates as the mouse is moved; optical sensors detect the motion and move the screen pointer correspondingly. An optical mouse is cordless and uses reflections from an LED to track the mouse's movement over a special reflective mat which is marked with a grid that acts as a frame of reference.
A common device that allows the user to reposition an arrow on their computer screen in order to activate desired applications. The term mouse comes from the appearance of the device, with the cord to the main computer being seen as a tail of sorts.
Note: The user usually sends signals to the computer when the user depresses or “clicks” a switch. A number of slang terms, such as “click on X” or “click and drag” have arisen from the appearance of symbols on a screen when a mouse is used.

Heb. 'akhbar, "swift digger"), properly the dormouse, the field-mouse (1 Sam. 6:4). In Lev. 11:29, Isa. 66:17 this word is used generically, and includes the jerboa (Mus jaculus), rat, hamster (Cricetus), which, though declared to be unclean animals, were eaten by the Arabs, and are still eaten by the Bedouins. It is said that no fewer than twenty-three species of this group ('akhbar=Arab. ferah) of animals inhabit Palestine. God "laid waste" the people of Ashdod by the terrible visitation of field-mice, which are like locusts in their destructive effects (1 Sam. 6:4, 11, 18). Herodotus, the Greek historian, accounts for the destruction of the army of Sennacherib (2 Kings 19:35) by saying that in the night thousands of mice invaded the camp and gnawed through the bow-strings, quivers, and shields, and thus left the Assyrians helpless.
