With Alt+Ctrl etc. modificators one has to take into account: many window
managers intercept some modificators globally for their own shortcuts. They
may be configured so per default, or the user can set his shortcuts and
later forget that he has done so. And then some shortcuts of an application
do not work, or work strange, nobody knows why...

...for example, Alt+Ctrl+Backspace kills the whole X11 together with all its
clients...
