Pagebreaks, space, footnotes, references, boxes, etc

• Page Breaks :- you can force a page break using \newpage.
• Preventing line breaks :- If there's a word that you don't want broken, put it in an mbox. E.g.,

  One shouldn't try to break up \mbox\emph{relationships}
  

• Space :-

  You can create vertical space \vspace{.5cm} between lines 
  or horizontal space \hspace{1.5cm} between words.

  between lines or horizontal space between words.

  The arguments to these commands can be negative. \vspace* will create space even at the top of a page. It's sometimes useful to create stretchable space. The following creates space that pushes the letters to the edge of the page

• Boxed Text :- For short pieces of text, use \fbox

     Help. I'm \fbox{trapped}
  

  Help. I'm

• Comments :- Anything to the right of a % character is ignored by L^ATEX .
