Sorry for the noise, but one more thing:

I overlooked that kate *does* make an effort to synchronize changes in KateMainWindow::editKeys(). \
However: 1) With the KXmlGuiClientSyncer this is no longer needed. 2) This only works for \
Settings->Configure Shortcuts, NOT when changing the shortcut via RMB-click directly in the menu. So when \
testing, please try changing shortcuts via RMB click.
