The hover() method specifies two functions to run when the mouse pointer hovers over the selected element, triggering the mouseenter and mouseleave events.

The keydown event occurs when a keyboard key is pressed down.

The keypress event occurs when a keyboard key is pressed down, but not for all keys (e.g. ALT, CTRL, SHIFT, ESC).

The keyup event occurs when a keyboard key is released after being pressed.

The mousedown event occurs when the left mouse button is pressed down over a selected element.

The mouseenter event occurs when the mouse pointer enters a selected element.

The mouseleave event occurs when the mouse pointer leaves a selected element.

The mousemove event occurs whenever the mouse pointer moves within a selected element.

The mouseout event occurs when the mouse pointer leaves a selected element.

The mouseover event occurs when the mouse pointer is over the selected element, and triggers even if over the element’s child element.

The mouseup event occurs when the left mouse button is released over a selected element.

The off() method is most often used to remove event handlers attached with the on() method.

The on() method attaches one or more event handlers to the selected elements and child elements.

The one() method attaches one or more event handlers for the selected elements, and specifies a function to run when the event occurs.

The $.proxy() method takes an existing function and returns a new one with a particular context.
