Tellico assigns an id integer to every entry. If entries are deleted,
the ID values won't be contiguous. The ID field just exposes the
internal ID value to the user. The @ symbol indicates an internal
value.

Derived fields can combine values from any field, but using
%{field-name} or %{field-title}. Coin collections, for example, use as
a title a combination of the year and mintmark of a coin. You can also
do some minimal selection from multiple values or number of
characters. See

Those capabilities aren't used very often. If you have suggestions for
expanding them, I'm be happy to hear them.
