since my first post at this blog 2 weeks ago, Appendix A is now twice as long (454 entries). Today i completed regex modifier, aiming now toward control chars and escape sequences. But not only the numbers improved, also quality improved much. There are now also more pointer to similar terms, tags when commands kept same since p5, etc. But I still need your help. So please have a look at these wiki pages and edit them if you have the feeling you can improve them.
