Bummer but thanks Charles.

This makes it sound like there is no way to guarantee browser and 
desktop component key sequences can be harmonized when the browser or 
desktop have already claimed them for another use. Is this correct or is 
there some other way to tell the browser and desktop "send these 
keystrokes to the web component for its use instead of claiming them"?


btw - it's probably clear now but the research mentioned below was all 
"book" based, not prototype testing.
