When KDE was upgraded to 3.4, its new accessibility features kicked in. However, this seriously interefered with how I use the keyboard, and I found myself performing the activation gestures that enable these features all the time without knowing it. This resulted in suddenly all written text appearing as CAPS, not being able to log in, not being able to authenticate to the screensaver etc without having a clue what's wrong. I think it would be good to mention these features in the release notes, along with how to turn the auto-activation off. The auto-activation lives in KDE Control Center -> Regional & Accessibility -> Accessibility -> Keyboard -> Use gestures for activating the above features.
Mentioned in overview that KDE 3.4 is included, with a note about the new accessibility features and where to control them. For FC4 final release. Thanks for the note!
