Currently, kscreen's kcm can only be configured by using the mouse (or maybe touch), using the keyboard is not possible. While this is only annoying for users who prefer the keyboard, it might be worse for the impaired or those who have only small/crappy touchscreens (which can be found on netbooks/smaller laptops.) I'm not a UX guy, so I don't know how and if the current settings can be enhanced with keyboard support, or if they need another approach, but providing them would be at least nice to have. Reproducible: Always
You are totally right, for "keyboard" fans we could do an exception but we should really really work for those who can't use a mouse. Going to upgrade the Importance

Everything in the KCM is keyboard-friendly except for two things: the screen grid, and the inability to tab to the Apply button. The latter issue is tracked with Bug 449328; let's use this for the former issue.
