The commands \listoffigures and \listoftables work in exactly the same way as \tableofcontents to automatically list all your tables and figures. If you use them, they normally go after the \tableofcontents command. The \tableofcontents command normally shows only numbered section headings, and only down to the level defined by the tocdepth counter, but you can add extra entries with the \addcontentsline command. For example if you use an unnumbered section heading command to start a preliminary piece of text like a Foreword or Preface, you can write:
Another way to end up with a lot of Sections is by working with a converted document (. Word Perfect, pdf, OpenOffice, Scanned Text) or text copied from a converted document or from a Web page. The conversion software aims to make a document in Word that looks like the original. However, there is no conversion software that handles Section formatting at all well, as far as I know as of January 1, 2014. This includes documents that started as Word documents, were converted to pdf, and then converted back. The conversion software can make every change or even apparent change in paragraph indents as a margin change. You can end up with a three-page document with fifty Sections!
The "Apply to:" choice of "This point forward" allows you to insert a continuous Section break where you are and make the rest of the current Section have the column settings you want. The default is "This Section." Another choice is to have the column layout apply to the entire document. The Start new column checkbox is one way to insert a column break before the bottom of the page. If you select the L eft or R ight column preset it unchecks the E qual column width setting. Line between inserts a vertical line between columns.
