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}".
{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}.
