The Single Line/Column Override minicalendar modifiers allow you to specify, for any individual minicalendar, whether that it is a single line/column minicalendar or not, even though the corresponding minicalendar option may be set to the opposite setting.
•To specify that the current minicalendar is a single line/column minicalendar, simply add :one to the end of any minicalendar marker.
•To specify that the current minicalendar is a multi-line (or square) minicalendar, simply add :sqr to the end of any minicalendar marker.
Adding these modifiers is the equivalent of setting the following options for the minicalendar to which this modifier belongs:
Note that this modifier cannot be used to specify the various options, particularly the special tabulations, to be used for one line/column minicalendars. These must be setup in the minicalendar options, even though you have later unchecked the single line/column checkbox.
