I've played with this a bit and so far it's handled all the
mouseover's I regularly deal with. One interesting thing I do notice
though is that, in the case of some mouseover popups, using the focus
mouseover object command is not strictly necessary, i.e. routing the
pointer to the object is sufficient and the mouseover object appears
directly where you are at in the page. Not all mouseovers act like
this however, in which case the focus command is very useful.
It might be preliminary but so far I'm having a lot more luck with
this than with any support for mouseovers I've seen anywhere else.
Keep up the good work, I for one appreciate all the effort that is put

I have just committed Orca's preliminary support for MouseOver objects
into git master. I want to stress "preliminary." <smile> In other
the most basic of mouseover objects (e.g. the image links in last.fm's
library page, the Friends link/menu in Facebook, the episode info in
Hulu queue) are handled. Nested items (such as menus within menus) is
still on our to-do list. And I've not seen all of the mouseovers you
might encounter to know what I failed to take into account. With that
disclaimer in mind, here's the deal:
There is a new command which will move focus to and away from the
which appeared as a result of hovering the mouse over an item in web
content. This command is bound to Orca+KP_Multiply for the Desktop
layout and Orca+0 in the laptop layout. The way you would take
of this command is to do the following:
1. Move focus to an object which you know/suspect has an associated
2. Route the pointer to that object using Orca+KP_Divide/Orca+9. If a
new mouseover object appears as a result, Orca should announce what it
3. If you think the new object that appeared might be of interest, you
can move focus to that new object with Orca+KP_Multiply/Orca+0.
4. You should be able to interact with the new object like any other
content. If you decide the mouse-over object is not of interest after
all, or if the mouse-over object merely presented information and
done reading it, you can press Orca+KP_Multiply/Orca+0 a second time.
This will move the mouse pointer back to where it was before you
it. The act of doing so should cause the mouse-over object to
Focus will then be restored to the object you were on prior to
the mouse over.
Known issues which are out of our hands:
1. At the moment, we have no way of finding out via at-spi if an
has an associated onMouseOver or not. It turns out there is already a
bug filed against Mozilla for the exposure of onMouse* stuff. Until
gets fixed, I'm afraid you really do have to know/suspect an object
2. If memory serves me, at least one Windows screen reader informs you
if the only change resulting from hovering the mouse over an object
one of visual appearance. From the cases I've looked at so far, I'm
seeing any events being exposed to us which we could use to implement
the same thing should doing so be desirable. The good news is that the
recently-added support for routing the pointer to the current object
seems to be reliable. In other words, if you route the mouse pointer
your current location in Firefox and Orca is silent, then you should
assume that no new objects resulted from the hovering.
For the rest of the issues, I've opened an uber-bug, i.e. a bug that
totally violates Orca community practice of "one issue per bug
The reason I did this was to make it easier for y'all to identify if
problem you're having with a mouseover on foo.com is actually just
another example of the problem being seen on bar.com -- and to make it
easier for me to look for patterns as I continue working on Orca's
mouseover support. That bug is:
Thanks! Looking forward to your feedback. Take care.
