I am working with the "exam" class by Philip Hirschhorn (version 2.704) and I am experiencing some trouble with the spacing of lists, itemize in my case, in solution environments. I see strong differences between the spacing in the "solutionbox" and the other solution environment but I am not proficient enough in lower level Latex or Tex to figure out the reason and potential solutions myself. I could make the lists behave the same by using "enumitem" with \setlist[itemize, 1]{nosep}. As far as I understand, this means that the list settings are actually changing between the different environments. I am interested in an explanation of the underlying mechanisms. Here is a minimum working example for you \documentclass[11pt, answers]{exam} \renewcommand{\solutiontitle}{% \textbf{Solution:}% \par% \noindent% } \begin{document} \textbf{Start of Document} \begin{questions} \question This is a solutionbox environment \begin{solutionbox}{5cm} The solution is either \begin{itemize} \item A \textbf{or} \item B \end{itemize} But it could also be C in a new paragraph. Or D in another new paragraph. \end{solutionbox} \question This is a solution environment \begin{solution} The solution is either \begin{itemize} \item Z \textbf{or} \item Y \end{itemize} But it could also be X in a new paragraph. Or W in another new paragraph. \end{solution} \end{questions} \textbf{End of Document} \end{document} You can see the difference in this screenshot montage it looks like the line spacing is identical but some lengths in the list environment are modified, such as \itemsep or \parsep The behavior of the solution environment is identical with the other solution environments (solutionorbox, etc.) as far as I see. The documentation says that the solutionbox environment is implemented differently from the other environments. I guess that this is part of the reason. Thanks in advance, Simon

I’m typesetting a document in Hungarian. Hungarian uses case suffixes / postpositions attached to the noun (e.g. ábra, ábrán, ábrára, táblázat, táblázaton), so I need to manually provide the inflected noun in running text. Additionally, I use the chemstyle package and I want scheme environments to behave like figures: same counter as figures (one shared sequence) same caption name (schemes should say “Ábra” in the caption, not “Scheme”) schemes should appear in the List of Figures This scheme/figure integration is already working; I include that code only because it’s part of the real setup. What I’m stuck on is a small helper macro for clickable references that lets me manually supply the Hungarian noun/suffix without duplicating it. \newcommand*\myref[2][ábra]{\hyperref[#2]{\ref*{#2}.~#1}} Desired output (whole text clickable) ábra ábrán táblázat táblázaton Current output (wrong: noun duplicated) ábra 1. ábra ábra 1. ábrán táblázat 1. táblázat táblázat 1. táblázaton Important: If I remove chemstyle (and the scheme-related unification code), then my referencing setup behaves as expected. The duplication issue appears only when chemstyle is loaded / schemes are involved.

I have the following code: \documentclass[tikz,border=5pt]{standalone} \begin{document} \ExplSyntaxOn \keys_define:nn {mykey} { foo .tl_set:N = \l_tmpa_tl } \keys_set:nn {mykey} { foo = {O\quad K},%<- } \begin{tikzpicture} \draw[dotted] (0,0) -- (2,0); \node[inner~sep=0pt] at (1,0) {\l_tmpa_tl}; \end{tikzpicture} \begin{tikzpicture} \draw[dotted] (0,0) -- (2,0); \node[fill=white,inner~sep=0pt] at (1,0) {\l_tmpa_tl}; \end{tikzpicture} \ExplSyntaxOff \begin{tikzpicture} \draw[dotted] (0,0) -- (2,0); \node[fill=white,inner sep=0pt] at (.7,0) {O}; \node[fill=white,inner sep=0pt] at (1.3,0) {K}; \end{tikzpicture} \end{document} For the sake of the template settings, the text O\quad K should be put as a token list, as a whole, but I need the third picture's result. Is that possible to just fill=white to just shade the "text area"? Edited: Since cfr commented for the original template case, I would provide more information. Claims: The original package is exam-zh package It depends on xeCJK, so xelatex is must I was not sure that whether it's CJK fonts settings works on every OS. See here. What I want, is to achieve something sealline style as below: It appeared in the leftmargin of exam paper: Now I have the following code: \documentclass{exam-zh} \usepackage{zhlipsum} % \ExplSyntaxOn % % Line 1487 in exam-zh.cls % % https://github.com/xkwxdyy/exam-zh/blob/main/exam-zh.cls#L1487-L1496 % \cs_set:Npn \__examzh_sealline_odd_text_around_line: % { % \node [ anchor = east ] % at ([xshift = -\g__examzh_sealline_odd_text_xshift_dim, yshift = \g__examzh_sealline_odd_text_yshift_dim]current~page~text~area.west) % { % \g__examzh_sealline_odd_text_format_tl % \__examzh_sealline_odd_spread_box:nn { \g__examzh_sealline_odd_text_width_dim } % { \g__examzh_sealline_odd_text_tl } % }; % } % \ExplSyntaxOff \examsetup{ sealline={ show=true, circle-show=false, line-type={loosely-dotted}, text={密封线},%<- the text here is put as `\g__examzh_sealline_odd_text_tl' text-format={\huge\bfseries}, line-thickness={2.5pt}, text-xshift={.375cm} } } \begin{document} \zhlipsum[name=zhufu] \end{document} That is the original case. Noted that 密封线, the l3keys sealline/text is put into \g__examzh_sealline_odd_text_tl ands \g__examzh_sealline_even_text_tl here(why I say as a whole). Which need to be processed by \__examzh_sealline_odd_spread_box:nn here. I want to change the present settings of exam-zh's setting code to the minimal extent.(Of course, I can type text={}, leave it empty, and follow \__examzh_sealline_odd_circle: here to draw multiple \node[fill=white] {密}s) But that change too much the package's setting. So, I simplified it to my origianl post😊.

I have a very long equation where the fraction line spans the whole equation, which makes it fit poorly in the IEEEtran format!

Can't find the way to write a hierarchical list in ConTeXt. it should be like 1. 1.1 1.1.2 2. 2.1 Only the first numbers of each hierarchy appear. Could anybody help, please?

I wanted TOC not to have section numbers displayed. So instead of using the star version of sections, found that simply adding \setcounter{secnumdepth}{0} does that. But then I found that once package titlesec was added, links inside the pdf no longer work. Here is MWE, which generates 10 sections and some subsection. Clicking on links in the PDF does nothing. Once titlesec is removed, all links work fine. \documentclass[12pt]{article} \usepackage{hyperref} \usepackage{titlesec} \usepackage{lipsum} \usepackage{luacode} \begin{luacode*}%this so I do not have to type 10 sections by hand function generateFewSections(n) local i for i = 1, n do s="\\section{section " .. i ..

Removing titlesec links work OK now. This only happens when adding \setcounter{secnumdepth}{0}. Removing this, then now titlesec does not cause any issue. If this by design or is there a bug here? Can I use \setcounter{secnumdepth}{0} and also use titlesec? TL 2025, updated about 2-3 weeks ago.

Consider the following MCE (say test.tex): \begin{filecontents*}[overwrite]{subfile} \documentclass{article} \newcommand{\foo}{foo} \begin{document} \foo{} \end{document} \end{filecontents*} \documentclass{article} \usepackage[subpreambles]{standalone} \usepackage{acro} \begin{document} \input{subfile} \end{document} The generated test.sta file: contains \newcommand {\foo }{foo}), is loaded two times (see test.log), but no complaint regarding a command \foo already defined. By contrast, the following MCE (again, say test.tex): \begin{filecontents*}[overwrite]{subfile} \documentclass{article} \DeclareAcronym{cd}{short = CD , long = compact disc} \begin{document} \ac{cd}. \end{document} \end{filecontents*} \documentclass{article} \usepackage[subpreambles]{standalone} \usepackage{acro} \begin{document} \input{subfile} \end{document} fails to compile at the 3rd run because of: (./test.sta !

In LaTeX, I wish to use a sequence of asterisk/obelus symbols ($\dagger$, $\ddagger$, $\ast_1$, $\ast_2$, $\ast_3$, ... ) within my equations and then reference them later in the text. See the following example: \documentclass{article} \usepackage{amsmath} \begin{document} \noindent Here is a minimal example of an equation: \begin{equation} \label{eq:parallelogram_law_like_inequality} \begin{alignedat}{3} \langle a, a-b \rangle &= &\;& \|a\|^2 - \langle a, b \rangle \\ &\leq_{\dagger} & & \|a\|^2 - \langle a, b \rangle + \frac{1}{2}\|b\|^2 \\ &= & & \frac{1}{2}\|a\|^2 + \frac{1}{2}\Big(\|a\|^2 - 2 \langle a, b \rangle + \|b\|^2 \Big)\\ &=_{\ddagger} & & \frac{1}{2} \|a\|^2 + \frac{1}{2}\|a-b\|^2 \end{alignedat} \end{equation} where $\dagger$ follows from blar and $\ddagger$ is an application of the blah blah. \end{document} However rather than manually matching up the different *1, *2, *3, ..., I would like to use some syntax along the lines of \note\label{note:blar} and later \ref{note:blar}. This should automatically enumerate the notes in the order they appear and create a hyperref target and link similarly to how equation/figure/table references work. What is the neatest way to achieve this? Thanks!

I want to create a command \isthisprime{<number>} where it decides whether <number> is or is not prime, and if it is, it also returns the order of the prime (eg, 2 is the first, 3 is the second, and so on). Here is my attempt at a code (excuse my choice of naming the counters): \documentclass{article} \usepackage{amsmath} \usepackage{enumitem} \usepackage{lipsum,blindtext} \newcount\div \newcount\divs \newcount\somnum \newcount\yes \newcount\yess \newcount\numberofprimes \newcommand{\isthisprime}[1]{% %Decide if #1 is prime \div=2 \yes=0 \ifnum#1<2 \yes=1 \fi \loop \ifnum\div<#1 \ifnum#1=\numexpr(#1/\div)*\div\relax \yes=1 \fi \advance\div by 1 \repeat \numberofprimes=0 \somnum=2 \yess=0 \divs=2 %Checking every number less than or equal to #1 \ifnum\yes=0 \loop \ifnum\somnum<\numexpr#1+1\relax \loop%checking if somnum is prime \ifnum\divs<\somnum \ifnum\somnum=\numexpr(\somnum/\divs)*\divs\relax \yess=1 \fi \advance\divs by 1 \repeat \ifnum\yess=0 \advance\numberofprimes by 1 \fi \yess=0\divs=2\advance\somnum by 1 \repeat \fi \ifnum\yes=0 #1 is a prime with index~\the\numberofprimes. \else #1 is not a prime. \fi } \begin{document} \isthisprime{101}\newline \isthisprime{102} \end{document} The idea: the first part of the code decides whether or not <number> is a prime; if it is we set the counter \yes=1, otherwise it remains equal to 0. So if \yes=1 we check every number less than or equal to <number> to see if it is prime or not. At every occurrence of prime, we increase the counter \numberof primes. Hence \numberofprimes will determine the order of <number>, if it prime that is. The part where it decides whether or not the input is prime or not is fine. However, it cannot find its order. It just says that the order is 1 if the input is prime. It cannot see what is wrong with my code, so I would appreciate any advice! Thank you in advance.

I have a (far from ideal) collection of macros that I \include in the preambles of my documents. It's very useful in giving my documents uniform semantic representation. For example, contravariant vector component functions all have a common appearance which I control globally. The down-side to this is that when I want to post an except to math.stackexchange.com, for example, I have to manually convert all of my LaTeX code into standard LaTeX which is independent of my preamble. Obviously the Tex-engine (e.g., lualatex) converts my macros into a form that TeX understands which is equivalent to standard LaTeX. Is there a tool that will take my customized LaTeX documents and convert them into standard LaTeX? Here's an example. (Please don't question the sanity of my notation. I have professionals for that.) \documentclass[a4paper,10pt]{article} \usepackage{amsmath} \newcommand{\CONST}[1]{\mathrm{#1}} \newcommand{\dd}{\CONST{d}} % differential d \newcommand{\DD}[2]{\frac{\dd#1}{\dd\CONST{#2}}} % derivative \newcommand{\PD}[2]{\frac{\partial #1}{\partial\CONST{#2}}} % partial derivative \begin{document} Written using my macros: \begin{align*} \dd f & = \PD{f}{x}\dd x + \PD{f}{y}\dd y.\\ \DD{f}{t} & = \PD{f}{x}\DD{x}{t}+\PD{f}{y}\DD{y}{t} \end{align*} What I want the tool to output: \begin{align*} \mathrm{d} f & = \frac{\partial f}{\partial \mathrm{x}} \mathrm{d} x + \frac{\partial f}{\partial \mathrm{y}} \mathrm{d} y.\\ \frac{\mathrm{d} f}{\mathrm{d}\mathrm{t}} & = \frac{\partial f}{\partial \mathrm{x}}\frac{\mathrm{d}x}{\mathrm{d}\mathrm{t}} +\frac{\partial f}{\partial \mathrm{y}}\frac{\mathrm{d}y}{\mathrm{d}\mathrm{t}} \end{align*} \end{document}

When I turn on headings for entries in index, I get the following error: ! LaTeX Error: Invalid UTF-8 byte sequence (�\check@icr). This is a minimal tex file: \documentclass{scrbook} \usepackage{splitidx} \usepackage[T1]{fontenc} \usepackage[utf8]{inputenc} \usepackage[ngerman]{babel} \makeindex \newindex[Index of Fruits]{fru} \begin{document} \sindex[fru]{Äpfel} \sindex[fru]{üzüm} \printindex[fru][Index of Fruits] \end{document} This is a minimal style file: headings_flag 1 heading_prefix "{\\textbf{" heading_suffix "}}\\nopagebreak\n" If I set headings_flag to 0 in the style file, I get no error messages. But the entries in index don't get headings in this case. In order to reproduce the same error, follow these steps: pdflatex file.tex splitindex file.idx -- -s style.ist pdflatex file.tex There is a similar question, which has no accepted answer.

I have answer blanks on an exam, and then I like to fill them in with the answers. Because the answer may need to be a displayed equation, I put it all in a parbox that gets underlined. This all works fine, until I try to enable tagging, at which point the displayed equation causes "Package tagpdf Error: The number of automatic begin and end text para hooks differ!" Is there a tagging friendly way to underline a parbox? \DocumentMetadata{lang=en-US,tagging=on} \documentclass{article} \begin{document} 1. \underline{\parbox{1in}{~}}\par 2. \underline{\parbox{1in}{\makebox[1in]{}}}\par 3. \underline{\parbox{1in}{okay}}\par 4. \underline{\parbox{1in}{$okay$}}\par 5. \underline{\parbox{1in}{\[not~okay\]}} \end{document}

Consider the following piece of code (MWE): \documentclass{article} \usepackage{siunitx} \usepackage{mathtools} \newcounter{A} \setcounter{A}{1} \begin{document} $\begin{array}{c} \text{\arabic{A}:} \text{\arabic{A}\stepcounter{A}:} \text{\arabic{A}\stepcounter{A}:} \text{\arabic{A}\stepcounter{A}:} \text{\arabic{A}\stepcounter{A}:} \end{array}$ \end{document} Compiling with the 2025 TeX distribution, it produces the following output: 1:2:6:10:14 which is very unexpected, since I just increment the counter A once by line. On the other hand: Compiling with the 2024 or 2023 TeX distribution yields the expected output 1:2:3:4:5 The expected output is also obtained if we swap the two line \usepackage{siunitx} and \usepackage{mathtools}. Can anyone explain this strange behavior to me?

i'm trying to do some geometric frieze with tikz. The last goal is to do a command to draw one of the 7 possible frieze (see wikipedia). But, first, i just do 1 frieze. Results: My code: \documentclass[tikz]{standalone} \begin{document} \newcommand{\footstep}[4]{ \begin{scope}[ xshift=#3cm, %for translation yshift=#4cm, %for translation xscale=#1, %for reflexion yscale=#2 %for reflexion ] \draw (1, 3) -- (1, 0); \draw (1, 0) -- (7, 0); \draw (6, 3) -- (7, 0); \draw (6, 3) -- (5, 0); \draw (5, 0) -- (4, 2); \draw (4, 2) -- (2, 0); \draw (2, 0) -- (1, 3); \end{scope} } \begin{tikzpicture}[rounded corners=1pt, very thick, scale=.75] \draw[help lines] (0,-1) grid (22,5); \footstep{1}{1}{0}{0} \footstep{1}{-1}{7}{3} \end{tikzpicture} \end{document} but i have to find the parameters by myself. I'd like something automatic. Something like : xshift = "scope width" yshift = "scope height" Thanks

I am trying to make an inline list using enumerate*, but it isn't working when trying to make a tagged document. I want the output to look like this: , but I am getting lonely item errors. Here is my minimal code that generates the error: \DocumentMetadata{lang=en-UK, tagging=on, pdfstandard=UA-2} \documentclass[a4paper,12pt,oneside]{book} \usepackage[inline]{enumitem} \begin{document} Therefore such ideas are expressed as: \begin{enumerate*}[label=(\roman*)] \item Suggestions \item Compulsions \item Delusions \item Pertrusions \item Overwhelming sense of righteousness \item Own by themselves where every entity is largely linked to another for its own survival. \end{enumerate*} \end{document} and here is the first bit of the the error in the .log: ! LaTeX Error: Lonely \item--perhaps a missing list environment. See the LaTeX manual or LaTeX Companion for explanation. Type H <return> for immediate help. ... l.11 \item S uggestions Try typing <return> to proceed. If that doesn't work, type X <return> to quit.

I am using the (awesome) acro package to manage my acronyms. Therefore, I want acronyms to be displayed in the pdf when hovering over them. acro supports this out of the box by using the pdfcomment package and the pdfcomments/use=true option. I always want to display the long form of the acronym, which is (in my case) always just text. So currently I'm using the following (for MWE see below): \DeclareAcronym{AI}{ short=AI, long=artificial intelligence, pdfcomment=artificial intelligence, } While this creates exactly the output I'm looking for (and I'll continue to use it, if not otherwise possible), it feels weird to insert the same text twice. As acro has served with perfect solutions to all my problems until now, I'm wondering whether there is a more elegant way to just use the long form for the pdf comments. Thank you in advance. Minimal Working Example (MWE): \documentclass{article} \usepackage{acro} \usepackage{pdfcomment} \acsetup{ pdfcomments/use=true, } \DeclareAcronym{AI}{ short=AI, long=artificial intelligence, pdfcomment=artificial intelligence, } \begin{document} Currently, the big thing is \ac{AI}. \end{document} Results in the following intended behavior:

I know how to use \draw (0,0) -- node[below]{X} (10,0); to put the text X in the middle below the line between the coordinates. What I would like to have is the very same, but without drawing the line, yet the following does not work (somewhat to my surprise :-/) \draw (0,0) node[below]{X} (10,0); I figured out a way involving node at ($ ...!.5!... $) yet \draw would sometimes be a bit more natural and I would in particular like to understand why it does not work, as I seem to miss some fundamental knowledge here.

In ltx-talk the default is for body text to be vertically centered. How to instead make it display always starting from the page top? Vertical centering makes the text jump around when I use the \only<..>{} command. That is, how to achieve what in Beamer I get with \beamer@centeredfalse? Here is an MWE. Between slides 1 and 2 the first paragraph jumps up. \DocumentMetadata{tagging = on} \documentclass{ltx-talk} \usepackage{blindtext} \begin{document} \begin{frame} \frametitle{Frame title} \blindtext \only<2>\blindtext \end{frame} \end{document}

Until a recent update, the following example used New Computer Modern book weight in the first paragraph and Latin Modern demibold in the second paragraph (confirmed with an older texlive in Overleaf). After the update, the BoldFont setting no longer seems to work and New Computer Modern bold is used. \documentclass{article} \usepackage{fontspec} \usepackage{kantlipsum} \setmainfont{NewCM10-Book.otf}[ BoldFont=lmromandemi10-regular.otf, ] \begin{document} \kant[1][1-2] \bfseries \kant[1][1-2] \end{document} I know there was some recent discussion around NewCM defaulting to Harf mode and not being able to override this due to the provided .fontspec files. Did something change so that setting BoldFont is no longer possible? Note that if NewCM10-Book.otf is changed to another font, say TeX Gyre Pagella, then the example works as expected.

So basically this time I was using overleaf again and came across this error: When I do \documentclass[11pt]{scrartcl} \usepackage[dvipsnames,svgnames]{xcolor} \usepackage[framemethod=TikZ]{mdframed} \usepackage{amsmath,amssymb,amsthm} \usepackage{thmtools} \mdfdefinestyle{mdgreenbox}{linecolor=ForestGreen,backgroundcolor=ForestGreen!5, linewidth=2pt,rightline=false,leftline=true,topline=false,bottomline=false,} \declaretheoremstyle[headfont=\bfseries\sffamily\color{ForestGreen!70!black}, mdframed={style=mdgreenbox},headpunct={.},]{thmgreenbox} \mdfdefinestyle{mdblackbox}{linecolor=black,backgroundcolor=RedViolet!5!gray!5, linewidth=3pt,rightline=false,leftline=true,topline=false,bottomline=false,} \declaretheoremstyle[mdframed={style=mdblackbox}]{thmblackbox} \declaretheorem[style=thmblackbox,name=Blah,numbered=no]{bla} \declaretheorem[style=thmgreenbox,name=Blahblah,numbered=no]{blah} \begin{document} \begin{bla} \begin{blah} Blah blah blah blah blah \end{blah} \begin{proof} blah blah blah blah blah \end{proof} \begin{itemize} \item Blah blah blah blah blah \item Blah blah blah blah blah \end{itemize} \end{bla} \end{document} It breaks and gives me which is just weird. The “Blah.” should be at the very front of the black box while the “Proof” should be right below the green. Also there is no bullet point for the first item in itemize. Surprisingly, If I remove the Blahblah section (the green box) everything comes out normally! (The blahs are edited from some content in my actual file)

I am trying to typeset a text in the Khanty language, whose orthography uses the Cyrillic script. I know how to make Cyrillic script work in the book project, but Khanty has the letter Ӆ ӆ (that's a Cyrillic lower case "L" with a tail: https://en.wikipedia.org/wiki/El_with_tail). I don't find a way to typeset this correctly. Does anyone have advice?

Why is my pgffor loop not iterating as expected? \documentclass{article} \usepackage{pgffor} \begin{document} \foreach \i[parse=true] in {0,pi/18,...,2*pi-pi/18} {works \i\\} \end{document} It only prints the first two elements of the sequence, but not the rest. It does however work when I evaluate the numbers first: \documentclass{article} \usepackage{pgffor} \usepackage{pgfmath} \begin{document} \pgfmathsetmacro{\a}{pi/18} \pgfmathsetmacro{\b}{2*pi-\a} \foreach \i[parse=true] in {0,\a,...,\b} {works \i\\} \end{document} I would expect parse = true to do this for me. Am I mistaken?

In this tikz MWE, why is the node placement not even close to pos=0.7 on a plotted curve? \documentclass[tikz,border=1cm]{standalone} \begin{document} \begin{tikzpicture} \draw[ domain = 0:2, samples = 100, variable = \y ] plot (\y*\y,\y) node[pos = 0.7, above left] {\(x=y^2\)} ; \end{tikzpicture} \end{document}

\def\drawDSID#1#2{ \def\trP{#2}\def\rpT{R}\def\trV{\ifx{\trP}{\rpT}3\else2\fi} \trV} The result is always 2, irrespective of #2, eg \drawDSID{(0,-7)}{R};

I am trying to use tcolorboxes to highlight exercises in a math tutorial (book document class) for a course I teach. I use a \label in the box hoping to reference the exercise by number in the solutions manual. However, the label does not "attach" to the colorbox; instead it returns the section number. Thus, Exercise "17" is referenced as "2.2.3" because that is the chapter section it is in. This behavior is different to that of a normal LaTeX environment and I am going in circles trying to resolve the issue. The tcolorbox manual is very detailed, but I cannot sort out this (seemingly) simple issue. What I want to accomplish is this: (1) create a box and put a \label{mylabel} in it. (2) \ref{mylabel} returns the box (exercise) number. (3) I want to reset the box numbering at the start of each chapter, with no "cross-talk" between the similarly numbered boxes in each chapter. I hope somebody can help restore my sanity and reveal the secret to doing this! Here is a MWE: \documentclass{article} \usepackage{tcolorbox} \tcbuselibrary{most} \begin{document} \section{Introduction} This document contains labeled tcolorboxes in Section \ref{sec:example}. The first box is numbered as \ref{box:label1}. \section{An Example Section} \label{sec:example} \newcounter{myboxcounter} \newtcolorbox[auto counter]{mybox}[1][]{ enhanced, colback=blue!5!white, colframe=blue!75!black, fonttitle=\bfseries, before title={\refstepcounter{myboxcounter}}, title={Exercise~\arabic{myboxcounter}\ifx#1\empty\else\ (#1)\fi}, fonttitle=\bfseries, breakable } \begin{mybox}[] \label{box:label1} This is box \ref{box:label1}. \end{mybox} \begin{mybox}[] \label{box:label2} This is box \ref{box:label2}. \end{mybox} \subsection{An Example Section} \begin{mybox}[] \label{box:label3} This is box \ref{box:label3}. The first two are boxes \ref{box:label1} and \ref{box:label2}. \end{mybox} \end{document}
