Meaning of 3.2 L3 SC2

Hi,

I thought about the meaning of 3.2 L3 SC2

   <q>Changes of context are initiated only by user action.</q>

with "change of context" being

   <q>A change of user agent, viewport, user interface controls,
   or focus; or complete change of content</q>

with respect to (X)HTML content.

I don't think this is meant to allow every change of context with each 
user action. So I produced a table with several user actions and 
permissible changes of context. See attached text file. What do you think?
