Cameron,

thanks so much for pointing me to Example: media01.svg

NB: the usual "Show this example" appears to be missing, and neither  
is the text of the title linked to a sample.

WCAG suggests avoiding use of "click" as it seems to assume a mouse  
is present.
obviously people who are blind may not be using a mouse.

The SVG 1.2 description of keyboard events appears very terse, it's  
copied below.

Is there a further enlarged description? for instance describing  
tabbing through focusable elements?

kind regards

Jonathan Chetwynd

13.6 Key events
http://www.w3.org/TR/SVGMobile12/interact.html#KeyrEvents

Note: The W3C's Web Content Accessibility Guidelines (WCAG) advise  
content creators to create device-independent content; in particular,  
content should not require that the user has access to a (full-size)  
keyboard.

User interface events that occur because of user actions that  
generate key presses (as opposed to text - for example, function  
keys, key presses for a game, etc) are called key events.

The example in section
http://www.w3.org/TR/SVGMobile12/multimedia.html#AudioElement
demonstrates this (media01.svg).  The audio begins when the button is
clicked.
