The ignore background options modifier is
:NoBa
This is useful, as shown in the example below when you want the extent of the background shading to be different than that of the textbox that contains the minicalendar elements.
The No Background modifier is applied to the larger box containing all the textual elements of the minicalendar (most noticeably the month name) and the minicalendar marker (in red) of the smaller box is left un-modified so that it can be shaded and/or framed when it is the current minicalendar, depending on the minicalendar options.
