A mouse usually controls the motion of a pointer in dimensions in a graphical user interface (GUI). The mouse turns movements of the hand backward and forward, left and right in to equivalent electronic signals that in turn are used to move the pointer.

The relative movements of the mouse on the surface are applied to the position of the pointer on the screen, which signals the point where actions of the user happen, so that the hand movements are replicated by the pointer.[22] Clicking or hovering (stopping movement while the cursor is within the bounds of an area) can select files, programs or actions from a list of names, or (in graphical interfaces) through tiny images called "icons" and other elements. For example, a text file might be represented by a picture of a paper laptop, and clicking while the cursor hovers this icon might cause a text editing program to open the file in a window.

  Click: pressing and releasing a button.
    (left) Single-click: clicking the main button.
    (left) Click two times: clicking the button times in quick succession counts as a different gesture than separate single clicks.
    (left) Triple-click: clicking the button times in quick succession.
    (left) Quadruple-click: clicking the button times in quick succession.

Different ways of operating the mouse cause specific things to happen in the GUI:
