VISUAL BOOK EDITOR
Overview
Book Editor is a Dynamic HTML (DHTML) editor designed for fast editing of HTML files. Book Editor is quite simple in usage because, on the one hand, it gives you a possibility to edit a file without viewing its HTML source and, on the other hand, you are able to see immediately the results of your corrections on the screen. So, if you want either to correct some book fragments or to add some text, comments, pictures, etc. to the main book content or even to create your own book, Book Editor provides relatively simple but efficient tools for you. Book Editor has two types of HTML editing tools:  for conventional users and for advanced users as well. The conventional user procedure is very simple: just select a text fragment to be edited, press the needed button, and you will see immediately the results of corrections. At the same time, an advanced user familiar with an HTML editing can access any html fragment of the book that allows to make direct changes of HTML file of the book.
Tricks with selection of text fragments 
Before performing of the most part of editing operations, you have to select a text fragment to be edited. HTML text editing is more sensitive to the selection choice that the conventional text editing. The main difference is that offen not only the text but also invisible HTML tags have to be included into the selection. However for most of the cases of practical concern it is usually enough to use the selection tricks below.
to select a word double-click on it.
to select an arbitrary text fragmet click on its start and then, holding Shift key, click on its end.
to select a paragraph click on it holding Ctrl key.
If you want to check HTML content of your selection, just run HTML Fragment Editor .
Tricks with typing
Book Designer supports two types of font setting: global and local. These settings include font type, font size, and font color settings. The global settings are assigned from the reader mode and affect all the book text. The local settings are assigned from the editor mode and affect the selected text. When you are typing, Book Designer keeps the last local settings for the text under typing. If you want to come back to the global settings, make a space, type the first letter of a new word starting from which you want to apply global settings, and press "Esc".
Example. Assume that your global settings are: font: Times New Roman, font size: small, color: blue. Using these settings you typed "global settings". Then you switched to:  font: Impact, font size: medium, color: red and typed "local settings". Now you want to type "back to global settings" using again the global font settings. To do it, type the first letter "b" of the word "back", press "Esc" and continue your typing. As a result you get:
To assign global settings for some text fragment, select it and press "Esc"
