Thanks so so much,
now I think I can master the photofocus. After I have photoread a book, then I try to activate after serveral hours. It seems that I can just read it faster than before. However, there are still many points that I can't call back from my subconscious.

I am wondering if I have to photoread again when i have this situation.Also, what is the feeling of performing efficent activation??

Thank you
Fung
