I want to avoid text being italicized when it's inside dollar signs. For example I want the Gal part of $Gal(f)$ to show as plain text, without having to write Gal$(f)$. How do I do this?  Thanks.

Mathematical operators, such as function names, should be set in roman type, not italics. Latex already has commands for some operators, including \max, \min, and \log.  How can I define additional such commands?

I typed up an assignment with a lot of numbers in LaTeX and turned it in to my adviser.  When he returned it to me with some corrections, one of which was a lot of $ around my numbers.  I understand that $ are necessary around some mathematical formulas, but I was just using numbers like -2 and 4.  I did not see any change in the font of the numbers when I added the $ either.  Since my adviser did not want to give me an explanation, what is the rationale?

I want to footnote a URL which contains mathematical signs such as = and LaTeX asks me for a $ sign to take it to mathematical space (and therefore changing the font which is not suitable). How should I overcome this situation, i.e. put url in footnotes without using a $ sign and evading mathematical space?

could anyone please tell me how I can write "ℰ" in latex in both text and math enviroment? I have already tried $\mathscr{E}$ and $\mathcal{E}$, but none of those are satisfying.   What I want to have is     but not any of these

I would like to pre-format the text in a form text-field, e.g. make it bold, italic or use a specific font. The following code generates a simple text-field:  \documentclass{scrreprt} \usepackage{hyperref} \begin{document} \textbf{The Text Field} \begin{Form} \TextField[]{\ } \end{Form} \end{document}   Is it possible to pre-format the text in the text-field? The hyperref package manual (10/2011) speaks of an optional parameter format and the use of JavaScript to format the field. Can this be used to format the text in the field? And if yes, how is it done? (I am not proficient in JavaScript)

I can't seem to find any consensus on the right way to typeset a differential operator, whether it is:   in a standalone context:  as part of a derivative:  as part of an integral:    In all of these cases, I have seen them sometimes italicized like variables (as in the second and third examples above) and sometimes not italicized like operator names (as in the first example above). There is also additional variation in how much spacing goes between the "d" and whatever it is acting on.  Seeing as this is an incredibly common symbol in many branches of mathematics, I am curious about the lack of standardization -- I've seen all possible combinations used in all possible contexts by many respected authors and publishers.  Are there any rules of thumb that I can follow? I personally tend to prefer the non-italicized version with very little space next to it, so I add:  \renewcommand{\d}[1]{\ensuremath{\operatorname{d}\!{#1}}}   to my default preamble, and use that everywhere, but I'd like to know if I'm breaking any hard-and-fast rules here.

I am trying to display vectors as bold and italic. The command \mathbf sets the letters non-italic. I also googled a bit and stumbled upon \mathbf{\em y} or \mathbfit{y}, which all didn't work.  I hope someone can help me on this.

I'm writing 'cause I would like to know if there's an automatic way (like something to put in the preamble) to make the subscript behave as double subscript: for example if I write   something_a    it should behave as   something_{_a}

I've heard that you should use \[ ... \] for displayed equations instead of  $$ ... $$, but why is that?  I'd assumed that it's so that you can more easily tell which are starting and which are ending delimiters, but if I always use a syntax-highlighting text editor, I can see that easily based on the color of the symbols.  Is there any reason for this suggestion?

Is there a way to use newcommand or some other nice technique to transform any occurence of  "bla"   in math mode into  \text{bla}   The reason I ask is because it is easy, and doesn't interrupt the flow of reading the (La)TeX code as much.  I would like to keep Xe(La)TeX's nice quote behavior (ie it can use the regular "" instead of backticks to quote some text outside math mode).

Is there a way to prevent \MakeUppercase from affecting in-text equations? In this example, abc should change to ABC, but n should be left as it is.   \documentclass{article} \begin{document} \MakeUppercase{abc $n$} \end{document}   The following works for individual characters, but I would like something more general.  \documentclass{article} \begin{document} \newcount\mycount \mycount\mathcode`n \MakeUppercase{abc $\mathchar\mycount$} \end{document}

I am using the 'article' class, 'figure' environment.  My captions are divided in two parts:   the information about the figure the credits of the figure (for which I use \textfff{})   In my list of figures, I would like to omit the second part. Would you have a solution, please?

I am curious as to whether there is an equivalent to the Alt-. command on Mac. On my computer it inserts the following character: ≥, instead of showing the .

What package should I use, or what setting can I make to the font in theorems so that the text wouldn't be italic. I use amsmath, and from default, everything I write in theorem environments becomes italic and I don't want that. Thank you

I was getting scope errors on a commutative diagram, and adding {} inside the quote marks eliminated the error. Why and under what circumstances are they needed.  This fails:   \ar[d, "\operatorname{g}_{\sigma_\beta}, \beta \prec \Beta_\gamma"]   This works:   \ar[d, "{\operatorname{g}_{\sigma_\beta}, \beta \prec \Beta_\gamma}"]

What special formatting tricks can be done in the comments now?  Proven:   **text** or __text__ = Bolding = text *text* or _text_ = Italics = text `text` = Code Formatting = text [example](http://example.com "title") Inline links with title and text http://example.com plain old links   Disproven:   Cannot insert &lt;kbd&gt; (i.e. F12) characters Cannot use #[text] to increase size

In math, one often needs to put a letter inside the symbols &lt;&gt;, e.g. to denote a cyclic group &lt;x&gt; generated by some element x. However, plain text displays the symbols &lt; and &gt; as an upside down exclamation point and an upside down question mark, respectively, while math type displays a large space like so:  &lt; x &gt;    Is there some way to reduce this spacing?
