Q: symbols and abbreviations

I have one suggestion.  The way Larry presents the
information is misleading in one important way.
You mention each possible use of each symbol
but do not indiacte the systems of oppositions
they enter into. Thus, it may be that in philology
some people use parens for what other people mark
with square brackets, but the information that is
missing is what the systems in use are.  This would
really be useful to have, esp. for those like me
who are not too familiar with said systems.  It
would also be good to be told which systems
are more widely used or considered standard.
