Show position of pointer when the Control key is pressed

Select this option to enable a mouse pointer animation when you press and release the Control key. This feature can assist you to locate the mouse pointer.

The position of the Control key on the keyboard can be modified in the Keyboard Layout Options dialog, see Seção 8.4.1.3 ― Opções de Disposição de Teclado.
Aceleração Use o controle deslizante para especificar a velocidade com que o cursor de seu mouse se movimenta na sua tela quando você move seu mouse.
Sensibilidade Use o controle deslizante para especificar o quanto o cursor de seu mouse é sensível aos movimentos de seu mouse.
Limiar Use o controle deslizante para especificar a distância que você deve mover um item antes que a ação do movimento seja interpretada como uma ação arrastar-e-soltar.
Tempo limite

Use o controle deslizante para especificar o período que pode se passar entre cliques quando você der um clique duplo. Se o intervalo entre o primeiro e o segundo clique exceder o tempo que está especificado aqui, a ação não será interpretada como um clique duplo.

Use o ícone de lâmpada elétrica para checar a sensibilidade do clique duplo: a luz brilhará brevemente a cada clique, mas ficará acesa com o clique duplo.

8.4.2.2 Mouse Accessibility Preferences

    Single click

    A single click of the primary mouse button

    Double click

    A double click of the primary mouse button

    Drag click

    A click that begins a drag operation
