Click
<hardware> 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.
