click (redirected from clack)

click

In phonetics, a suction sound made in the mouth. Click sounds occur in various African languages and are often used as interjections in other languages—for example, the sound of disapproval represented in English by tsk, tsk. Clicks are a regular part of the consonant system in the Khoisan languages and in Bantu languages such as Xhosa and Zulu that have been strongly influenced by Khoisan.

(hardware)

click - To press and release a button on a mouse or other pointing device. This generates an event, also specifying the screen position, which is processed by the window manager or application program. On a mouse with more than one button, the unqualified term usually implies pressing the left-most button (with the right index finger), other buttons would be qualified, e.g. "right-click". Multiple clicks in quick succession, e.g. a double-click, often have a different meaning from slow single clicks. Keyboard modifiers may also be used, e.g. "shift-click", meaning to hold down the shift key on the keyboard while clicking the mouse button. If the mouse moves while the button is pressed then this is a drag.
