// The shortcut's default values are given as QKeySequence for being able
// to use platform independent standard keys (QKeySequence::StandardKey).
// However, converting key sequences into QVariants does not seem to be
// revertible.  In addition the related string (which is saved in the
// preferences file) can not be determined during compile time since the
// result depends on the platform (at least in case of standard key sequences
// like, e.g., QKeySequence::Copy)
// Therefore, these prefs for key sequences require a separate constant
// definition and value method for the settings class.
