General ⇒ \newcommand and \newcommand<>

[zyjheng]

I'm using Miktex with TexnicCenter. I'm confused. What's the difference between \newcommand and \newcommand<> ? I found the latter in some tex using beamer. Another question is what does \TH do? It says \TH has been defined when I tried to newcommand \TH.

Thank you~

Hi zyjheng,

welcome to the board!

What's the difference between \newcommand and \newcommand<> ?

The beamer class extends the syntax of \newcommand. It's documented in the beamer user guide 9.6.1 Making Commands and Environments Overlay-Specification-Aware.

what does \TH do?

\TH will print the letter thorn.

Thanks a lot Stefan.

I searched on internet and found that I should use \usepackage[T1]{fontenv} to print \TH. Now I can recommand it. Ha...

Thanks again.
