Article: LaTeX (pronounced "LAY-tech" or "LAH-tech") is a typesetting application that converts text files into formatted documents. To use LaTeX, you must first create a document in a text editor program with instructions telling LaTeX what type of document you have and where the actual document text begins. These instructions are command that begin with the backslash (\) character. Specify the type of document with the "\documentclass" command, with the type of document specified in braces. For an article, the command would read "\documentclass {article}". (Do not include the quotation marks; they are used here to set off the example.) Specify where the text portion begins with the command "egin {document}". The braces indicate the starting and stopping places for formatting the text as specified by the formatting command. You can nest several formatting commands, such as having a large block of italicized text with a portion within it in boldface. If you do nest commands, be sure to use as many close braces as you do open braces to ensure that the text is formatted the way you want. A sentence with the last word italicized would read as follows: "One of the first TV shows to realistically depict the routine of patrol officers was extit {Adam-12}."
