This keyword adds a window with one to five switch boxes,
where exactly one box can be selected. This allows to choose between up to five exclusive options,
you must specify a general explanation for the user and then one additional text for every switch box.
Example for a menu with two switch boxes:
MainMenu: Options
PullDownMenu: _R_eport error
SwitchBoxMenu2: Concretize the error
Text: Did the problem occur right now?
Text: _Y_es, I did not exit YASARA since then.
Text: _N_o, just before, I had to restart YASARA to get here.
