The dblclick event is fired when a pointing device button (usually a mouse button) is clicked twice on a single element.

The DOMContentLoaded event is fired when the initial HTML document has been completely loaded and parsed, without waiting for stylesheets, images, and subframes to finish loading. A very different event load should be used only to detect a fully-loaded page.

It is an incredibly common mistake to use load where DOMContentLoaded would be much more appropriate, so be cautious.

The keydown event is raised when the user presses a keyboard key.

The keypress event should be raised when the user presses a key on the keyboard. However, not all browsers fire keypress events for certain keys.

Webkit-based browsers (Google Chrome and Safari, for example) do not fire keypress events on the arrow keys. Firefox does not fire keypress events on modifier keys like SHIFT.

The keyup event is raised when the user releases a key that's been pressed.

The onload property of the GlobalEventHandlers mixin is an event handler for the load event of a Window, XMLHttpRequest, element, etc., which fires when the resource has loaded.

The mousedown event is raised when the user presses the mouse button.

The mouseenter event is fired when a pointing device (usually a mouse) is moved over the element that has the listener attached.

Similar to mouseover, it differs in that it doesn't bubble and that it isn't sent when the pointer is moved from one of its descendants' physical space to its own physical space.

With deep hierarchies, the amount of mouseenter events sent can be quite huge and cause significant performance problems. In such cases, it is better to listen for mouseover events.

The mouseleave event is fired when the pointer of a pointing device (usually a mouse) is moved out of an element.

mouseleave and mouseout are similar but differ in that mouseleave does not bubble and mouseout does.

This means that mouseleave is fired when the pointer has exited the element and all of its descendants, whereas mouseout is fired when the pointer leaves the element or leaves one of the element's descendants (even if the pointer is still within the element).

The mousemove event is raised when the user moves the mouse.

The mouseout event is raised when the mouse leaves an element (e.g, when the mouse moves off of an image in the web page, the mouseout event is raised for that image element).

The mouseover event is raised when the user moves the mouse over a particular element.

The mouseup event is raised when the user releases the mouse button.
