Hi,
1. Here's what Jim recommends to suppress page numbers:
(below is the entry that should be added to Pronunciation Editor [Options->Pronunciation Editor])
Word: {{re=(\r\n\s*)p\.\s*\d+\s*(\r\n)}}
Pronunciation: <s>
Please see initial Jim's post for details :
viewtopic.php?f=11&t=32692. There IS an automation to split books by chapters.
You may just need to go File->File Splitter Utility, choose appropriate "Split Method" (to split by chapters you'd need to select "By Specified String in Input File"), then type in the string you need (e.g., CHAPTER in case each chapter starts with the word "CHAPTER") into the box named "Comma delimited list of strings", and then press the "Split" button.
The described procedure will get your file split into chapters (provided that you have not missed to first select the file you want to split by clicking the "Browse" button next to "Input File Path" and selecting the file, then specifying the "Output Directory" and then the "Base Output Filename"), resultant files (each containing only one chapter) being saved in the the Output Directory.
You may feel free to experiment with this file splitter procedure as the initial file will always be kept intact.
