It should be there in the built-in help with the entry " CSS Applications->Display->Best OPI, Yet->Rules". If it is not there, you may need to download the latest version.

Cheers,

Subject: Re: CSS/BOY macro substitution problem

Hi Xihui,

I was sure I did use the BOY preference settings to set the default
macro value but apparently I didn't. Thanks for that solution - it works
the way I want it to.

The second issue has been resolved as well. Thank you. However, I was
wondering whether the rules were documented somewhere? I couldn't find
anything about them in the built-in help documentation.

Cheers,
Pawel
