global shortcut resolution (the KGlobalAccel methods) work on application level, X11 as far as I can tell does not have a method to tell which application has grabbed a key (to fill KGlobalShortcutInfo). other than that no configuration interface for global shortcuts (not by KGlobalAccel itself, plasma and its applets have interface for that), also the shortcuts interface did not and still does not handle global shortcuts well so that is something to look into. one of the problems solved with this change is the fact that multiple plasma applets (e.g. multiple instances of the keyboard applet) could not use the same shortcut, now it is possible. as for which applet gets the shortcut action it is the one that has the grab first - that is how key grabbing works in X11 Signed-off-by: Ivailo Monev <xakepa10@gmail.com>
