KeyboardEvent class
objects describe a user interaction with the keyboard; each
event describes a single interaction between the user and a key
(or combination of a key with modifier keys) on the keyboard. The
event type (keydown, keypress, or keyup) identifies what
kind of keyboard activity occurred.
Note: events just indicate what interaction the user had with a
key on the keyboard at a low level, providing no contextual
meaning to that interaction. When you need to handle text input,
use the input event instead. Keyboard events may not be fired
if the user is using an alternate means of entering text, such as
a handwriting system on a tablet or graphics tablet.
