No.  Do your own homework.

Resource/document; _not_ “link”.  The (hyper)link is the *reference* to the 
resource/document instead.

It does not.

Why do you want to avoid using the keydown/keyup events?

You should read more carefully.  With the above you *create* the keyboard 
event object (and can simulate keypresses by dispatching it to elements).  

You need to use the keyboard event object that the runtime environment 
creates for you, and dispatches to your event listener, instead.
