Comment 3 for bug 342567

This second patch needs custom strings, documentation, translation work and the like. With some work it could behave quite smoothly.

In this case, actions are simply stripped from the notifications so we still get notification bubbles, but to deactivate (or activate) the functionality the user must press the same keys again. Personally, I find it works better than the dialog since by the time the dialog displays, sticky / slow keys is activated. That can make things quite confusing for a user if he is trying to click the Deactivate button after having pressed, for example, Alt. (Besides, why have a confirmation dialog when it has already happened?).
Right now the title text still reads like a confirmation dialog, which could be a tad confusing. In theory, it could just be stripped and we use the main text as the only text in the notificaiton.
