Text Formatting ⇒ Making a font smaller -not matter the context

[betaz]

Hi guys,

I wish to know if there is a way to change the font size respect the context. Suppose that I've a command to write Hello, called \hello. The usual staff to do is

Code: Select all

\newcommand{\hello}{Hel{\small lo}}

Now I want to put it in different contexts, like:

Code: Select all

\section{\hello everybody!}
\subsection{This is another \hello world program}
From the math point of way, 
$$ x_{\textrm{\hello}} = x^2 $$

I don't want this output (the small part being equal-sized all over the places):
Hello everybody!
This is another Hello
From the math point of way,
xHello = x^2

Any ideas?

Thanks in advance,
Beta

Hi Beta,

you could use the relsize package with its commands \larger, \smaller, \textlarger, etc.
