Thanks Victor. I was initially wondering if the problem was a question 
of navigation "mode" myself. Instead, it seems that if we release a 
right arrow key to the firefox browser, the caret moves one character to 
the right. I am wondering if we need to preserve this user expectation?  
For example I think the orca developers look for caret-moved events and 
speak the new character.  Also note shift-right arrow is often used for 
adding a character to the right, to the currently selected text.
