When Main and subheadings are swapped, sometimes there are one or more ignored words at the beginning or end of the subheading. Usually, for the swapped headings to read correctly, the ignored word(s) must not only be kept in the subheading field, they must also be swapped from the front to the back or from the back to the front of the new subheading. The SmartSwap feature of SKY Index lets you specify which ignored words will be swapped in this manner and which will not.
