## ﻿LaTeX math mode and mbox mode

According to a doc I found around

An \mbox within math mode does not use the current math font; rather it uses the typeface of the surrounding running text.

In math mode, I would like to write something like a_{\mbox{foo}}. If I use this, the foo will be quite big, too big. If I write a_{foo}, foo will be in italic.

What is the magic trick to have non-italic, small text?

## 1:

How do I correctly insert an image/figure and have the text “flow around” the image/figure in latex?
I personally prefer to use the \text{} command provided by the AMS-LaTeX package.

Use of the verbatim environment inside a macro
To use this, you need to include the statement.
glossaries package and footnote in LaTeX
\usepackage{amsmath} 
somewhere in your document preamble, and then in any mathematical environment,.
How to include a code snippet in a beamer presentation?
a_{\text{foo}} 
will produce the desired output.

\includeonly not working as expected with newclude
Section 6 of the User’s Guide for the amsmath Package mentions that the \mbox{} equivalent is.
Multicol and a floating box at the top of page, with text wrapping around it
a_{\mbox{\scriptsize foo}} 
A final option is.
What are the options to get \mathcal working for lower case letters?
a_{\mathrm{foo}} 
which is what I used before I discovered AMS-LaTeX and the \text{} command..

## 2:

I usually use the option a_{\rm foo} since this is the shortest form I am aware of.

I'm not sure if there are any caveats though.

I guess the proper form is using the form a_{\text{foo}} suggested by las3rjock.

## 3:

You can just type a_{\text{foo}}. I did not try, but it should work. EDIT: as las3rjock said, the \text{.} is provided by the AMS-LaTeX package.

So you need to add the \usepackage{amsmath}.

## 4:

You can use the similar commands \mathmbox or \mathmakebox provided by the mathtools package..
