Mouse Down

The mouse down event occurs when the user presses a mouse button over an element (does not necessarily need to release the mouse click over the same element).

1. The mouse pointer goes over an element

2. The mouse button is clicked over an element

So, when the user’s mouse goes over the element within the application, the user proceeds to the next step. If the Next button is disabled, the user does not have any choice but to select the element.

Note: Mouse click and mouse down are different. The mouse click event is fired only when a full click happens. Full click is when the mouse button is pressed and released while the pointer (mouse) is still over the same element. The mouse down fires as soon as the button is initially pressed even if the user does not release it or releases it over a different element.
