I've started using Linux quite recently and although I've tried many distros, I've always ended up using KDE, coz I find it the most user friendly. There is however something I would like to change if possible. Whenever I want to reboot/logout/etc. there is a confirmation screen with a countdown, and if I misclick the OK button it's interpreted as if I pressed the Cancel button. Is there a way to customize this screen to disregard these misclicks?

In case you want my reasoning: I'm using this computer as a media PC connected to a TV which I'm controling from the bed so the surface is not the most optimal for the mouse.
