Given I debugged this earlier and can't think of any nicer solution, would 
be useful for you..

This comes from 
kde:plasma-integration/src/platformtheme/kdeplatformtheme.cpp

QList<QKeySequence> KdePlatformTheme::keyBindings(QKeySequence::StandardKey 
key) const

I think this binds the KStandardActions to those keybindings.. So instead 
of listening to clicked best would be to use 
http://api.kde.org/frameworks-api/frameworks5-apidocs/kconfigwidgets/html/namespaceKStandardAction.html

Maybe others might have good solution.

Thanks
