How to set the font generated from a beamer latex file to Times New Roman in preamble?

Thanks!

Just go here: http://www.ctan.org/tex-archive/info/Free_Math_Font_Survey/survey.html, choose the most similar font to the one you want and add

\includepackage{fontname}

in the preamble

you can try also with \includepackage{times} but I don't know if it's the font you want..

I found the solution thanks to the link in Vincent's answer.

 \renewcommand{\familydefault}{\sfdefault}

This changes the default font family to sans-serif.

add the following to you preamble:

\newcommand{\newCommandName}{text to insert}

Then you can just use \newCommandName{} in the text

For more info on \newcommand, see e.g. wikibooks

Example:

\documentclass{article}
\newcommand\x{30}
\begin{document}
\x
\end{document}

Output:
