Version: 1.0 (using KDE 4.3.0) OS: Linux Installed from: Ubuntu Packages When you navigate in the tree by using the keyboard it should be possible to open the corresponding settings by pressing ENTER.
I can confirm this issue. Pressing Enter when navigating the System Settings treeview does not load the appropriate component in the main window.
This is actually a bug, and will be fixed shortly.
