Working Group Resolution (LC-2810):
Thank you for your comment.  

According to our testing, onkeypress is not redundant to onclick for
non-native HTML controls, that is, for HTML elements that are not natively
focusable.  If a developer makes an image clickable with onclick that item
does not respond to keyboard events unless onkeypress is provided.  

It is accurate that the author does need to control the script so that the
appropriate keypress is accepted and other keypresses are ignored, but this
is detailed in the example's description.  

We would welcome an onmousedown/onkeydown example if you or others wish to
provide one to be added to this technique.

The description of the technique does not currently draw the distinction
between native and non-native HTML controls, which is confusing. We have
updated the technique to make this clearer:

[DONE] Change Note 1 to: "Although click is in principle a mouse event
handler, most HTML and XHTML user agents also process this event when a
native HTML control (e.g. a button or a link) is activated, regardless of
whether it was activated with the mouse or the keyboard. In practice,
therefore, it is not necessary to duplicate this event when adding handlers
to natively focusable HTML elements. However, it is necessary when adding
handlers to other events, such as in Example 2 below.
