Slavek, All,
On my last 3.5.13-sru build, the input gesture pressing print-screen for ksnapshot stopped working similar to what happened with R14. Please test the latest 3.5.13-sru build and see if it still works for you. The entire issue might be a simple 'k' 't' rename issue and 3.5.13-sru may have pulled in that commit. I'll have more time this weekend to dig into it, but having confirmation on if other see it as well will help :)
