If you wish to insert a forced vertical skip, insert an ert containing either smallskip, medskip, bigskip or a fixed vspacelen where you specify len. For a fixedhard, single blank line, use vspacebaselineskip (roughly the same as bigskip). The other lengths that were mentioned are softer and allow for some stretchshrink. Include a blank line between a centered title (using begin center. Using the as a line skip, latex gave me an error indicating that.). Include a blank line between a centered title (using begin center. Using the as a line skip, latex gave me an error indicating that.). The same as vspacebigskipamount, ordinarily about one line space, with stretch and shrink. The default for the book and article classes is 12pt plus 4pt minus 4pt. The same as vspacemedskipamount, ordinarily about half of a line space, with stretch and shrink. The linebreak command tells latex to break the current line at the point of the command. With the optional argument, number, you can convert the linebreak command from a demand to a request. Line and paragraph spacing fixed vertical spaces nsmallskip a small vertical space follows this line. Answer (1 of 6) easy way to comment many lines in latex is to use iffalse and fi. For ex codedocumentclass11pt,a4paperarticle begindocument this a test document. Notice that to start a new paragraph you have to insert a blank line in between them.
