Sorry, I planned to answer but did not find the time.

LyXAction is the dictionary of known LyX functions, with their names and
properties (together with FuncCode.h for the enums).

LyXFunc contains the basic mechanism to execute these functions. It
should soon become a variable-less class, and part of its contents will
be moved somewhere else. This is in flux currently.

FuncRequest is the object that describes the action one wants to
execute.

FuncStatus describes the result of the action, in particular the updates
that need to happen.

Is this description clear?
