The printed manual that comes with the beetles CD has sections 'Using
Advanced Mode' and 'Further Hints on Using Intkey'. These sections are
brief, but it is stated that:
Full documentation is available in Intkey in Advanced Mode. The
documentation is also included on the CD-ROM in the MS-Word file
intkey.doc located in the root directory. A viewer for MS-Word
files is in the directory \wordview.
In the current version of Intkey, the 'Include Taxa' function is
available in Normal Mode.

All of the morphological characters of these families have overlapping
values; for example
Transverse occipital ridge or carina
absent; or present
By default, these overlapping values are not counted as differences. To
find them, set the 'Match' parameter to 'Exact' (or 'Unknown
Inapplicable', if you don't want unrecorded or inapplicable values
counted as differences).
The 'Differences' button was supposed to temporarily set 'Match' to
'Unknown Inapplicable', but was not doing so. (Thanks for drawing this
bug to our attention; it has now been fixed.) You can work around the
problem by setting 'Match' explicitly; or you can use the latest version

However, the combined taxon is in DELTA format, and you need the
complete DELTA package to make it available in Intkey. (This is how the
subdivided families were combined into single units.)
Although Intkey's capabilities are far ahead of any other interactive
key program (see http://biodiversity.uno.edu/delta/www/comparison.htm),
we are well aware of many ways in which it could be improved.
Unfortunately, we have so far not been able to obtain funding for
