HTML Event Methods
Events are normally used in combination with functions, and the function will not be executed before the event occurs (such as when a user clicks a button).
HTML DOM Event Methods
|Returns true if a specified key is activated
|Returns an array containing target ranges that will be affected by the insertion/deletion
|Cancels the event if it is cancelable, meaning that the default action that belongs to the event will not occur
|Prevents other listeners of the same event from being called
|Prevents further propagation of an event during event flow
