I'm trying to create a LaTex document which has a "testday" and a verse full of "testItemToDo" and I want any page break to occur before the "testday" but never between a "testday" and the verse of "testItemToDo". So, we like to say that LyX gives you WYSIWYM editing. However, the proper way with LyX is to tell the computer what the text is, not what it should look like. Of course you can also still do some low-level formatting for fine-tuning. Cut some paragraphs from an old document and paste them in a completely different one, and LyX does the rest. LyX does the renumbering for you, adds the section to the Table of Contents, and more! Because you tell LyX what kind default of document you're editing and what type of paragraph this-or-that text is, the computer can typeset it accordingly. You could even pick a section, heading and all, up out of one document and drop it in a new one. No longer do you need to scroll through a 75 page document, changing all of the section numbers because you deleted an old section. This gives you far more power than you may think. With LyX, you simply choose a so-called "paragraph environment." Recalling what font you used for all of your section headings isn't your problem anymore. Remembering which number to use for the next subsection isn't your problem anymore. So, line- and page-breaks aren't your problem anymore. The answer is simple: you shouldn't, and with LyX, you don't have to. , when a computer can do all of that for you?
Why should you do extra work remembering which subsubsection in which section in which chapter you're in, what numbering scheme your using, how big the different headings are, what font you used for the different types of headings, and so on, and so on, and so on. Besides, computers are best at following a set of rules, and doing so repeatedly and consistently. There's no need to reinvent the wheel, after all. This is a simple introduction to using LYX, written mainly for students and academic staff.
While LyX contains everything it needs to be a comfortable user interface, the typesetting program contains everything necessary to format text, and do so very, very well. LYX is the answer to this problem you tell it what to do, and it decides how it will look on the page, leaving you free to concentrate on actually writing words, rather than messing around with tabs and font sizes. However, that's not really necessary, since LyX uses a separate typesetter program to perform the final formatting of your text. "Almost" means that the line- and page-breaks are not displayed exactly as they will appear in the printed document. LyX provides an "almost-WYSIWYG" view of the document. It's also difficult to read these documents before they have been printed. As a result, you get no visual feedback until you feed your document to the LaTeX program.
With plain LaTeX, you need to enter a series of typesetting commands into the text in order to produce your document. What prevents some people from using this powerful, free typesetting system, one that is available for almost every computer system, is its difficult usage. LaTeX is equally good for writing letters, articles, books, or any other kind of document, and does so much better than common word processors. So, some people claim that its main purpose is mathematical typesetting. For example, it's difficult to find a mathematics or computer science book that is not done with LaTeX. LaTeX is used for a wide range of documents, especially in science. LyX uses the most popular and, in our opinion, best typesetting system available: LaTeX. Technically this is done by combining the comfortable interface of a word processor with the high quality of a real typesetting system. With LyX, the author can concentrate on the contents of her writing, since the computer takes care of the look. Compared to common word processors, LyX will increase productivity a lot, since the job of typesetting is done mostly by the computer, not the author. Today I managed to get working in LyX table 'floats' that break over multiple pages. This seems to be normal behaviour for LaTeX 1. I've tried to use longtables in the subfloats, but compilation fails.
It is designed for authors who want professional output quickly with a minimum of effort without becoming specialists in typesetting. page-because of the length of the subtables-, it will not break. LyX is a free program that provides a more modern approach to writing documents with a computer, an approach that breaks with the obsolete tradition of the "typewriter concept."
