Hello,

  I have run into a problem......I need a little help:

Question:
     If I want to use the tab to move thur site....
     and as each link is reached it is highlighted
     or made bold...etc...the problem is I can not 
     use the mouse to touch the SVG Canvas to get 
     focus on the graphic......Does anyone know if this
     is possible with Adobe ASV?...If you want to take up the
     the challenge you can not use the mouse in any way!!
     Remember the point is not to use the mouse......in fact
     unplug the mouse and try to do this....this is the challenge!!!
      

"Tabbing order" refers to the linear sequence in which users 
accessing a site via keyboard may navigate through links or form 
controls on a Web page. The navigation through the page using the TAB 
key is important for individuals who cannot use a pointing device.

  All features in Internet Explorer are accessible to you by using 
the keyboard or the mouse. 

With Internet Explorer, you can explore the Web by using the 
keyboard. Just press TAB and SHIFT+TAB to move forward and backward 
between screen elements

I do not know about other Browsers.....but this is a pretty much a 
standard feature....

Question:
    I is there a reason that Adobe Viewer does not have this tab 
functionality build in...or .....am I missing something....like an 
attribute?

Here is some code to play with....try to tab....nothing that I can 
tell is happening.....maybe I am doing something wrong :-(
 
<?xml version="1.0" ?>
<svg xmlns:xlink="http://www.w3.org/1999/xlink">
<title>SVG link problem</title>
<desc>The default behavior of HTML browsers is to 
      outline or highlight the link in some way as client
      tabs through the document....Adobe's Viewer
      does not do this....I would like to highlight
      or underline...etc. the links on the page in order
      they appear on the page as the client tabs though the page..
      I guess you could switch the order....extra credit for that:-)
      remember you can not touch your mouse to make this work...
      that includes clicking the first time to receive focus on
      the SVG Canvas!!!!!!

Thank you for anyone that comes up with a solution...a lot of people 
will benifit from this solution :-)
