the display of any packets pertaining to NAKed transactions.

This function decreases the size of the displayed elements, allowing more (but smaller) packet
fields per screen. This function is also available as an icon in the toolbar.

This function causes the current element size to be used as the default value upon subsequent
invocations of the CATC Detective analyzer.
