This was a timely question for me, since I'm dealing with some of the same
things. What I wanted to do was to move the virtual cursor to a particular
place.
I have a case where the vc is in one place. And, you activate this treeview
type of control, and pick an item in the treeview. When you do that, text
changes in another part of the page, to reflect the selection. And, there
is no convenient way, so far, of flipping over to that other place.
We are adapting this requirements management tool, called Contour.
A wizzy friend of mine got this tool called Grease Monkey, which is a
pluggin for Firefox. With that tool, he was able to add Aria tags to the
incoming HTML, as long as we use firefox. Part of that was what I think are
called relationships. Basically, it draws a connection between two
elements, no matter where they sit on the page. And, there is a new jaws
function, MoveToControlledTarget. I don't know if this relationship is
biDirectional, can't recall. But, if the virtual cursor is on one end of
this relationship, and you execute MoveToControlledElement, the VC will move
to the companion control. So, that has been helpful.
But, this markup script for Greese Monkey is kind of hard to create if you
don't already pretty well understand what is going on. And, quite honestly,
I can't say I do.
But, in general, what I wanted to do was to somehow navigate the DOM in
script land, get to some element, and force the virtual cursor to go there.

I a not sure I understand what you are asking...
However, if you want to determine the active element that the browser is
focused on you can do this via the DOM. This works in IE:
Var
Object o,
Object element
o = IEGetCurrentDocument ()
element = o.activeElement
; you can see the HTML of this element:
html = element.outerHTML
If you want to do the opposite which is to move the browser to a control,
assuming it can receive focus such as an input control and you know the ID
of it you can do this via the DOM also.
o = IEGetCurrentDocument ()
element = o.getElementById(htmlID)
element.setFocus()

apps?
Thanks to many of you up here, who so kindly told me about the,
"SetJawsFindText", and "JawsFindNext" functions, I now have been able to
set up some lovely shortCut keys for the user to very quickly locate and
activate buttons in his new Web-based front end customer service system.
And that's so far workin a treat!
:)
However, I'd like to go a level deeper now, and be able to learn how I might
least invasively, but most efficiently/robustly, locate and bring PCCursor
focus to,a given control, (or "element" I think is the term used in Web
land?) rather than just blindly using virtual find to locate text on a page.
Since sometimes, of course, text being looked for, using virtual find
mechanisms, may occur both as an element label, and as non-clickable plain
text on the page.
And sometimes, as in this case, even as part of other Same type elements!
E.g. suppose I have an edit field, whose label is "search," but there are
several other occurrances of the word "search" on the page.
Not only this, but there is at least one other edit field element labelled
"favorite searches," which would of course get picked up on any
StringContains deal.
What would people suggest might be some code snippets/ideas/methodologies I
might try, to accomplish tooling through elements looking for this
particular edit control, whose label is merely the word "Search," and
nothing else?
Thanks much for any tips anyone would care to share on this one?
