That would be the ideal situation, but I wonder whether it is possible to achieve it. I remember the situation with the onscreen keyboard GOK. It seemed to be targeted mainly at switch users and that fonctionality was hindering pointer users to have a smooth experience with it.
Moreover, GOK had a lot of options; do we really want to confront pointer users with options they do not need or do not even understand? You might reply that it might be possible to hide options according to its usage; but that will probably not be easy; especially if we also want a zeroconf onscreen keyboard.
By the way, what is the steno chording layout?

Yesterday, I wrote an email to the ayatana dev mailing list about the issue, but have not got any reply yet. I wonder whether it arrived at destination as it seems to be a dev only mailing list.
marmuta, the person who has done most of the development lately on onboard has a bit of time at the moment for onboard. Do you know who we should contact in order to solve the issue?

Does anybody of the accessibility team attend these discussions in order to make sure that the accessibility aspects are also taken care of?

The onboard source package shipped with desktop files that would make onboard appear under the Universal Access menu. However, when packaged to create the deb, the source was always patched in order to have the Universal Access menu hidden by default.
I have not investigated yet, but since Unity, that changed the method of launching applications, this might not be necessary anymore.

I would say both situations are quite bad for the affected users.
A real dwell user normally is not able to click; thus we cannot count on him to produce a click with some hardware device to enable dwelling (dwelling=automatic clicking after a timeout).
That is why I propose an item that itself reacts on dwelling to start the dwelling feature. The dwell applet for the gnome-panel had such an item, but as I already mentioned in my previous email, it was only a partial solution. Indeed:
- It was a solution only for the desktop session, not for the login screen. (On computers with only one user, a work around was to enable automatic login.)
- It was not a solution out of the box, as somebody able to click by hardware had to install the dwell applet on the panel, before a dwell user could use it.
For the sake of completness, the old GDM offered another approach to start some accessibility tools at the login screen: the user had to perform specific gestures with the pointer on the screen and depending on the gesture, a determined accessibility tool was started.This is not a good solution in my opinion, because there is no clue on the screen about the gesture feature and also no information about what gestures to perform. We are far away from an intuitive and obvious solution here.
