I'm trying to get something like this (taken from Microsoft Word): The left cell is going to be "fixed", meaning it shouldn't grow with the text filling the right one; viceversa, the right cell should adapt to the text put in it, but: being at least as high as the left cell with the background for the entire cell the table should take horizontally all of the \textwidth optionally, the left cell should have a minimum height For now I kinda managed to get this, with LuaLaTeX (1): \documentclass{report} \usepackage{tabularx} \usepackage{multirow} \usepackage[table]{xcolor} \usepackage{lipsum} \begin{document} \noindent\begin{tabularx}{\textwidth}[h]{p{6cm} >{\columncolor{gray}}X} {\cellcolor{red}\color{white}\textbf{Title of boxed section:}} & \multirow[t]{2}{=}{\lipsum[1]} \\ & \end{tabularx} \lipsum[1] \end{document} but as you see it overlaps both in the right cell, and with the rest of the text: We can use LuaLaTeX and LaTeX3. Do you have any advise? Thanks! (1) EDIT: added \usepackage{...} to provide complete MWE

I recently noticed a bug, where the TikZ backgrounds library ignores any other options applied within the same scope definition. As you can see in the MWE below, I have a scope on the background layer with the additional options blue and ultra thick, which are ignored. \documentclass{standalone} \usepackage{tikz} \usetikzlibrary{backgrounds} \begin{document} \begin{tikzpicture} \draw[red, ultra thick] (0,0) -- (2,0); \begin{scope}[on background layer,blue,ultra thick] \draw (1,-1) -- (1,1); \end{scope} \end{tikzpicture} \end{document} Using nested scopes or defining the options directly in the path definition gives the desired result. \documentclass{standalone} \usepackage{tikz} \usetikzlibrary{backgrounds} \begin{document} \begin{tikzpicture} \draw[red, ultra thick] (0,0) -- (2,0); \begin{scope}[on background layer] \begin{scope}[blue,ultra thick] \draw (1,-1) -- (1,1); \end{scope} \end{scope} \end{tikzpicture} \end{document} Is this a bug? It isn't mentioned in the manual. I couldn't find a git repo to report an issue, so I hope this is the right place to ask.

I am using the "shorttitle" field with "biblatex" to handle the removal of articles (like "the") in French in some cases. The problem is that, as a result, the "citetitle" function uses the "shorttitle" attribute by default instead of the full title. How can I get to use full title by default? Here is the MWE: \documentclass{scrartcl} \usepackage{polyglossia} \setdefaultlanguage{french} \usepackage[ backend=biber, citestyle=verbose-trad2, ]{biblatex} \usepackage{filecontents} \DeclareCiteCommand\citeshorttitle {\usebibmacro{prenote}} {\mkbibemph{\printfield{shorttitle}}} {\multicitedelim} {\usebibmacro{postnote}} \begin{filecontents}{\jobname.bib} @book{Constitution, title = {La Constitution}, shorttitle = {Constitution}} \end{filecontents} \addbibresource{\jobname.bib} \nocite{*} \begin{document} The short title is \citeshorttitle{Constitution} but \texttt{citetitle} also becomes \citetitle{Constitution} instead of \emph{La Constitution}. \end{document}

I have two rectangular TikZ nodes placed one below the other: B1 is above B2. I would like to create a third rectangular node B3, shifted to the right in the x-direction, such that: the top of B3 is aligned with B1.north the bottom of B3 is aligned with B2.south I am not sure what is the best TikZ way to do this cleanly. Here is a minimal example of the situation: \documentclass{standalone} \usepackage{tikz} \usetikzlibrary{calc} \begin{document} \tikzstyle{block} = [draw, fill=white, rectangle, inner xsep=0pt, align=center, font=\small]% \begin{tikzpicture} \node [block, text width=3em] (B1) {Block 1}; \node [block, anchor=north, text width=3em] (B2) at ([yshift=-5em]B1.south) {Block 2}; \node [block, anchor=west] (B3) at ([xshift=5em]$(B1.east)!0.5!(B2.east)$) {Block 3}; \end{tikzpicture} \end{document} I tried using minimum height with coordinate differences, but I could not make it work properly. What is the recommended approach?

I'm trying to print a table from a csv loaded with datatool, but have it display in groups - by which I mean (in the below example), the column 'group' should only have one entry per group, with 'data' repeated. In other words, no group name should appear twice. What I've done is to define (and re-define) a macro at the end of the loop to update to the latest group, then pass that to \DTLifstringeq. I've checked that the \lasttype is being updated each iteration by adding it's value to the printout table - it is. But despite it being the current value, the string comparison isn't working. The MWE \documentclass[12pt]{report} \usepackage{datatool} \usepackage{array} % Required for p{} columns \usepackage{tabularx} % Optional: for auto-width columns \usepackage{booktabs} % better tables \usepackage{longtable} % tables breaking across pages \usepackage{multirow} \usepackage{xstring} \usepackage{filecontents} \begin{filecontents*}{test.csv} group,data Thing1,something Thing1,somethingelse Thing1,somethingother Thing1,somethingsomething Thing2,newthing Thing2,newotherthing Thing2,newthirdthing Thing2,lastthing \end{filecontents*} \begin{document} % Load datatables % Load datatables \DTLread[name=test]{test.csv} % Define this BEFORE the longtable \newcommand{\lasttype}{} \begin{longtable}{l l} \toprule Group & Data\\ \midrule \endfirsthead \multicolumn{2}{l}{\textit{(continued)}} \\ \toprule Group & Data\\ \midrule \endhead \bottomrule \endlastfoot \gdef\lasttype{}% Reset tracker at the start of the table \DTLforeach{test}{ \group=group, \data=data }{% \DTLifstringeq{\group}{\lasttype}{ % Same type, leave first column empty & \data \\ }{% % New type, print it and update tracker GLOBALLY \group & \data \\ \gdef\lasttype{\group} } } \end{longtable} \end{document} If there's a better way to do it, that's great, but I'd love to know what the \DTLifstringeq isn't working when (as far as I can tell), I've literally just defined the two strings to be the same.

What is the reason of why I can haven't the colors? \documentclass{article} \usepackage{xcolor} \usepackage{lucide-icons} \begin{document} \lucideicon{alarm-clock-check} \textcolor{red}{\lucideicon{alarm-clock-check}} \end{document}

How to make rounded corner and curve (..controls?) for this path (or similar)? \documentclass[margin={1.5cm 1,5cm 1.5cm 1.5cm}]{standalone} \usepackage{tikz} \begin{document} \begin{tikzpicture} \fill[cyan] (0,0)--(2,0)--(5,2)--(7,3)--(6,4)--(4,7)--(2,7)--(.5,5)--(0,2)--cycle; \end{tikzpicture} \end{document}

I am debugging somebody else's .tex file. The first line is: %&xx I also see files xx.fmt and xx.tex in the same folder. What does this line mean ? Is it like \input ? But apparently faster (I guess it includes a pre-compiled represemtation of the .tex file),is it ? The file xx.tex loads a number of packages, which makes it slow to compile. I guess the intention might have been to speed up the compilation. I am trying to compile the file that I am debugging with pdflatex (MikTex on Windows-10) . Strangely, pdflatex does not even produce a .log file -- Iguess it fails before that?

As a follow-up to this question here, I'd like to redefine \backrefxxx so that multiple back-references are formatted as they are on Wikipedia: I tried the following command: \renewcommand{\backrefxxx}[3]{\textasciicircum \textsuperscript{\hyperlink{page.#1}{#1}}} Minimum working example: \documentclass{article} \usepackage[pagebackref]{hyperref} \renewcommand{\backrefxxx}[3]{\textasciicircum \textsuperscript{\hyperlink{page.#1}{#1}}} \begin{document} \cite{fml2026} \newpage \cite{fml2026} \begin{thebibliography}{1} \bibitem{fml2026} First M.~Last. \newblock Title. \newblock {\em Journal}, 2026. \end{thebibliography} \end{document} but this produces the format: ${\textasciicircum}^{1,2}$ Question: Is it possible to achieve the Wikipedia format where the back-reference goes back to exact location and not just the page?

I'm trying to write a multi-file using simultaneously the subfiles and fancyhdr packages. My main.tex file is \documentclass[a4paper]{article} \usepackage{graphicx} % Required for inserting images \graphicspath{{images/}} \usepackage[utf8]{inputenc} \usepackage[T1]{fontenc} \usepackage[brazil]{babel} \usepackage[top=190pt,head=80pt,headsep=50pt,bottom=110pt,footskip=50pt]{geometry} \usepackage{fancyhdr} \usepackage{array} \usepackage{subfiles} \title{Title} \author{Author} \date{Somewhere in the past} \begin{document} \maketitle \newpage \section{Introduction} Odd stuffs \section{Good morning} \subfile{sections/section.tex} \end{document} and the section.tex file is \documentclass[../main.tex]{subfiles} \graphicspath{{\subfix{../images/}}} \begin{document} \pagestyle{fancy} \fancyhf{} \fancyhead[C]{ \huge \renewcommand{\arraystretch}{1.4} \begin{tabular}{|>{\centering}m{0.19\textwidth}|m{0.74\textwidth}<{\centering}|} \hline {\textbf{N-0}} & {\textbf{Header Title}} \\ \hline \end{tabular} } \fancyfoot[C]{% \begin{tabular}{|m{0.5\textwidth}|>{\centering}m{0.2\textwidth}|m{0.2\textwidth}<{\centering}|} \hline {Laboratory of Strange Stuff & Version 1 & {Page \thepage}} \\ \hline {{Stranger Stuffs} & {a} & {b} } \\ \hline \end{tabular} } \textbf{Hello world!} \end{document} When I compile the sub-file section.tex, the fancyhdr package runs fine and I get a customized header and footer. When I compile main.tex, the header and footer are absent. Is there a way to customize the header this way? I want to create a lot of sub-files, all with the same header format, but each one with its own header title.

I'm running into a rather bizarre issue with \ShellEscape from the shellesc package. When running the following command with both CMD and PowerShell on Windows 11 curl.exe -G "https://simbad.u-strasbg.fr/simbad/sim-tap/sync" --data-urlencode "REQUEST=doQuery" --data-urlencode "LANG=ADQL" --data-urlencode "FORMAT=text" --data-urlencode "QUERY=SELECT dec, ra FROM basic WHERE main_id = 'NGC2024'" -o query.txt I get the expected output in the .txtfile dec | ra -------------------|----------------- -1.8416666666666668|85.42916666666667 However, when I run it using \ShellEscape (basically \immediate\write18 with pdflatex), the request fails due to the single quote chars around NGC2024 being gobbled, resulting in a non-TeX-related error. Using LuaLaTeX with os.execute does not fix this issue. I also tried replacing ' with %27 and swapping single quote and double quote chars with no effect. Placing the command in a .bat file and writing \ShellEscape{query.bat} does work, however. I highly suspect the error comes from the interaction of \write18 with my machine, but I'm still confused as to how to fix it. MWE: % arara: pdflatex: { shell: true } \documentclass{article} \usepackage{shellesc} \ShellEscape{% curl.exe -G "https://simbad.u-strasbg.fr/simbad/sim-tap/sync" --data-urlencode "REQUEST=doQuery" --data-urlencode "LANG=ADQL" --data-urlencode "FORMAT=text" --data-urlencode "QUERY=SELECT dec, ra FROM basic WHERE main_id = 'NGC2024'" -o query.txt } \begin{document} Test \end{document} Log file: This is pdfTeX, Version 3.141592653-2.6-1.40.29 (TeX Live 2026) (preloaded format=pdflatex 2026.3.7) 15 APR 2026 15:16 entering extended mode \write18 enabled. %&-line parsing enabled. **query-astro.tex (./query-astro.tex LaTeX2e <2025-11-01> L3 programming layer <2026-01-19> ...

I'm using $\widehat{.}$ and $\widetilde{.}$ in my text for ordinals. As I'm sometimes using subscripts I decided to just always go with these instead of $\hat{.}$ or $\tilde{.}$ as $\hat{x_{n+1}}$ doesn't look good at all. Furthermore, the wide versions look noticably different from the regular ones, such that I would consider it bad notation to switch between both. I only treat \widehat in the following, but the problems I mention also arise with widetilde. Problem 1) Even for ordinals \widehat{.} interferes with brackets (and \hat{.} too, for that matter). I tried to be smart and simply define a new command \what{.} using mathop, mathbin etc. but only \newcommand{\what}[1]{\mathpunct{\widehat{#1}}} fixes the bracket interference (kind of). It's not a solution though, as it interferes with the spacing of \what{t}\in\what{S} and \what{t}', and the space added is not equally distributed. Question 1) Is there a solution here that fixes the spacing issue of \widehat{.} with brackets, while not interfering with \what{t}\in\what{S} and \what{t}'? Problem 2) Defining an equivalence relation on my widehat-versions, I thought \widehat{=} would be a good idea - intuitive notation, at least for me. However, here the spacing again becomes problematic, when comparing t=t to t \widehat{=} t. I figured from one of egreg's answers that I can fix this by defining \newcommand{\whrel}[1]{\mathrel{\widehat{#1}}} and this indeed works. Question 2) Answers to Question 1) will likely not fix t \widehat{=} t. Do I really need to define different commands? I am using \newcommand{\quasiequal}{\whrel{=}}, which I don't intend to change, so this is more of a general question. Is there nothing like a \mathwhatever{.} that specifies "take the spacing of whatever you're using widehat on, and potentially add equal spacing on both sides to keep brackets at bay"? If so, why? Here is a MWE: \documentclass{article} \newcommand{\what}[1]{\mathpunct{\widehat{#1}}}% \newcommand{\wtil}[1]{\mathpunct{\widetilde{#1}}}% %\mathord, \mathop etc. don't work for keeping brackets at bay \newcommand{\whrel}[1]{\mathrel{\widehat{#1}}}%for relations \newcommand{\whord}[1]{\mathord{\widehat{#1}}}%for ordinals \begin{document} hat: $(\hat{t})$ bracket interference. Also, compare $t=t$ to $t \hat{=} t$. widehat: $(\widehat{t})$ bracket interference. $\widehat{t}\in\widehat{S}$, $\widehat{t}'$ look fine. But $t=t$, $t \widehat{=} t$. what: Fixes $(\what{t})$ kinda. But $t=t$, $t \what{=} t$, $t\in S$, $\what{t}\in\what{S}$, $t'$, $\what{t}'$. wtil: Fixes $(\wtil{t})$ kinda. But $t=t$, $t \wtil{=} t$, $t\in S$, $\wtil{t}\in\wtil{S}$, $t'$, $\wtil{t}'$. whrel: Fixes $t \whrel{=} t$. whord: Keeps $\whord{t}\in\whord{S}$ and $\whord{t}'$ but doesn't fix $(\whord{t})$. \end{document}

It is possible that either the package does not behave as I expect, or I am misunderstanding how to use it correctly. According to the manual, the inequality 3x + 2y - 6 >= 0 should represent the half-plane above the line 3x + 2y - 6 = 0, i.e., the region containing points such as (0,3). However, in my code the line is drawn correctly (it passes through (0,3) and (2,0)), but the shaded region does not match the expected half-plane: it appears on the opposite side of the line. What am I doing wrong when using \LinearInequality? Is it a sign convention issue, an internal convention of the package, or do I need to rewrite the expression in a different form to obtain the correct shaded region? \documentclass{article} \usepackage{tkz-grapheur} \begin{document} \begin{GraphTikz}[ x=1cm, y=1cm, Xmin=-3,Xmax=3, Ymin=-3,Ymax=3 ] \DrawAxisGrids[Font=\small]{auto}{auto} \LinearInequality[color=pink,hatch={north east lines}]{3x+2y-6}{>=0} \end{GraphTikz} \end{document}

I'm using a per-chapter bibliography. I would like to disregard the margin note spacing, and make full use of the page. Using a two page layout is making this hard.

I want to use \str_set_convert:Nnnn with Japanese chars directly in document. The MWE below has no problem in pdfLaTeX.

I'm going to have a printed version of my ltx-talk that won't have color. I would still like to have \alert do something, however.

Under normal circumstances, BibLaTeX uses the same coordinating conjunction "and" for two authors that may have their names in one script (Latin, for now) and also to join two translator names that could have their names in another script (Cyrillic in this example). You may change the scripts above to any other pair and the problem remains the same. This has the unfortunate consequence of placing a pair of names in English joined by a Russian conjunction in the text as seen here: generated by the simple MWE: \documentclass{article} \begin{filecontents}[overwrite]{isaac.bib} @BOOK{isaacson:en, author = {Isaacson, Eugene and Keller, Herbert Bishop}, title = {Analysis of Numerical Methods}, publisher = {Dover Publications}, address = {Mineola, New York}, year = {1994}, langid = {english}, } @BOOK{isaacson:ru, author = {Isaacson, Eugene and Keller, Herbert Bishop}, title = {Анализ численных методов}, author-ru = {Э.

My code snippets: \renewcommand{\chaptermark}[1]{\markboth{\scshape\chaptername\ \thechapter. #1}{}}% \renewcommand{\sectionmark}[1]{\markright{\scshape\S\thesection. #1}}% worked just fine in TeXLive 2022 (using amsbook format in LaTeX), but in TeXLive 2026 the section heads do not appear at all.

We say $\alpha$ is regular if $\alpha'(t)\ne 0$ for all $t\in I$. We can imagine a particle moving along the path $\alpha$, with its position at time $t$ given by $\alpha(t)$. As we learned in vector calculus, $$\alpha'(t) = \lim_{h\to 0}\frac{\alpha(t+h)-\alpha(t)}h$$ is the velocity of the particle at time $t$. The velocity vector $\alpha'(t)$ is tangent to the curve at $\alpha(t)$ and its length, $\|\alpha'(t)\|$, is the speed of the particle. We say a vector function $f\: (a,b)\to\mathbb R^3$ is $C^k$ ($k=0,1,2,\dots$) if $f$ and its first $k$ derivatives, $f'$, $f''$, \dots, $f^{(k)}$, exist and are all continuous.

We shall now see that we can associate to each smooth ($C^3$) arclength-parametrized curve $\alpha$ a natural ``moving frame" (an orthonormal basis for $\mathbb R^3$ chosen at each point on the curve, adapted to the geometry of the curve as much as possible). We begin with a fact from vector calculus that will appear throughout this course. Suppose $f, g: (a,b)\to\mathbb R^3$ are differentiable and satisfy $f(t)\cdot g(t)=\text{const}$ for all $t$. Then $f'(t)\cdot g(t) = -f(t)\cdot g'(t)$. In particular, $$\|f(t)\|=\text{const} \quad\text{if and only if}\quad f(t)\cdot f'(t)=0 \quad\text{for all }t\,.$$ What distinguishes a circle or a helix from a line is their curvature, i.e., the tendency of the curve to change direction.

I have been looking into switching my lecture presentations from Beamer to ltx-talk for the automatic tagging functionality. For frame titles, the default behavior does not vertically center the text in the colored header/banner. Here is a minimum working example (most recent release of MacTeX). % !TEX TS-program = lualatex \DocumentMetadata{tagging=on} \documentclass{ltx-talk} \EditInstance{header}{std}{ background-color = blue!50, color = white, } \author{John Doe PhD} \title{An interesting title} \institute{Interesting Conference} \begin{document} \begin{frame} \maketitle[framestyle = wallpaper] \end{frame} \begin{frame} \frametitle{Frame title not vertically centered in colored header} Some text \ldots \end{frame} \end{document} Does anyone know how to achieve a frame title that is vertically centered in the header/banner when using ltx-talk?

I am using exam clas with liguistix package to create an exam paper in Marathi. As English has base line, the Devanagari script used for writing Marathi has head-line or Shiro-rekha (ꣻꣻꣻ). As in english the space for an answer is provided using an \hrulefill command which is at the position of base line of Latin characters, I wan to use Shiro-rekha for providing answering space for Marathi text. I can type the shiro-rekha character many times (like this: ꣻꣻꣻꣻꣻꣻꣻꣻꣻꣻꣻꣻꣻꣻꣻꣻꣻꣻ) to fill the space. But it will take time and will be unevenly filled. Is there any way to use this shiro-rekha character and get filled it like a hrulefill? My MWE is as bellow: \documentclass{exam} \usepackage{linguistix} \linguistix{languages={english,marathi}} \begin{document} \makebox[\textwidth]{\textsc{संपूर्ण नाव : } ꣻꣻꣻꣻꣻꣻꣻꣻꣻꣻꣻꣻꣻꣻꣻꣻꣻꣻꣻꣻꣻꣻꣻꣻꣻꣻꣻꣻꣻꣻꣻꣻꣻꣻꣻꣻꣻꣻꣻꣻꣻꣻꣻꣻꣻꣻ} \vspace{0.2in} \makebox[\textwidth]{\textsc{Full name:}\enspace\hrulefill} \end{document}

I'm using a two-column extarticle document, without multicol. How do I make these two plots in a {figure} environment right-aligned instead of left-aligned in the column? They are a part of a nested list in my actual document so I did the same in the code here; other than the lorem ipsum, those are the same figures I'm using in my actual document. My goal with making them right-aligned is to align the left-hand side of the plots with the text following them. \documentclass[twocolumn]{extarticle} \usepackage{pgfplots, lipsum} \usepackage[margin=1cm]{geometry} \pgfplotsset{compat=1.18} \begin{document} \lipsum[1-5] \begin{enumerate} \item \begin{enumerate} \item \lipsum[1] \begin{figure} \label{fig:3sinx+2-x} \begin{tikzpicture} \begin{axis}[ xlabel=$x$, ylabel=$f(x)$, xmin=-0.5, xmax=2*pi+0.5, ymin=-6.25, ymax=6.25, xtick={0, pi/4, pi/2, 3*pi/4, pi, 5*pi/4, 3*pi/2, 7*pi/4, 2*pi}, xticklabels={$0$, , $\frac{\pi}{2}$, , $\pi$, , $\frac{3\pi}{2}$, , $2\pi$}, ytick={-6, -5, -4, -3, -2, -1, 0, 1, 2, 3, 4, 5, 6}, yticklabels={$-6$, , $-4$, , $-2$, , $0$, , $2$, , $4$, , $6$}, axis lines=middle, width=5.5cm, title={$f(x) = 3\sin(x)+2-x$} ] \addplot[ color=red, domain=0:2*pi, smooth ]{3*sin(deg(x)) + 2 - x}; \end{axis} \end{tikzpicture} \label{fig:3sinx+x-3} \begin{tikzpicture} \begin{axis}[ xlabel=$x$, ylabel=$f(x)$, xmin=-0.5, xmax=2*pi+0.5, ymin=-4.25, ymax=4.25, xtick={0, pi/4, pi/2, 3*pi/4, pi, 5*pi/4, 3*pi/2, 7*pi/4, 2*pi}, xticklabels={$0$, , $\frac{\pi}{2}$, , $\pi$, , $\frac{3\pi}{2}$, , $2\pi$}, ytick={-4, -3, -2, -1, 0, 1, 2, 3, 4}, yticklabels={$-4$, $-3$, $-2$, $-1$, $0$, $1$, $2$, $3$, $4$}, axis lines=middle, width=5.5cm, title={$f(x) = 3\sin(x)+x-3$} ] \addplot[ color=red, domain=0:2*pi, smooth ]{3*sin(deg(x)) + x - 3}; \end{axis} \end{tikzpicture} \end{figure} \item \lipsum[1-2] \end{enumerate} \end{enumerate} \end{document}

I am trying to graph a system of 3 inequalities in 3 dimensions. These ineuqalities are: y-z>=1/2x, x-z>=0, and x+y>=3z. Currently I am struggling to get even a basic output.

I have been trying to understand what is behind this warning: Package biblatex Warning: Patching footnotes failed. (biblatex) Footnote detection will not work. which is produced by, for example, this code: % !TeX program = lualatex \DocumentMetadata{ uncompress, lang=en, tagging=on, pdfstandard=UA-2, pdfstandard=A-4f, tagging-setup={math/setup={mathml-SE,mathml-AF}, extra-modules={verbatim-mo, verbatim-af}} } \documentclass[12pt]{report} \usepackage{setspace} \usepackage{biblatex} \begin{document} Example. \end{document} Searching on this forum for similar issues, I am led to believe this has to do with the (re)definition of \@footnotetext. What confounds me, however, is that I can only produce this warning if I simultaneously set up the \DocumentMetadata, include setspace, and use biblatex. In other words, if I remove either the \DocumentMetadata or setspace then I no longer get this warning. (I don't know if this is worth mentioning, but for what it's worth, I originally also use hyperref in the document where I found this issue-- its inclusion seems to have no bearing on this behavior).

While I know that I can use % to comment out a line of code, I would like to get the same result (i.e. non-compiling text) in the middle of a block of text, like this (the brackets are here just to show the example): Blabla blabla bla bla bla [some non-compiling comments] bla bla blabla blab I don't want to write something like the following (i.e splitting the text paragraph): Blabla blabla bla bla bla % some non-compiling comments bla bla blabla blab Is it possible? I guess that I'll need to use some non-compiling macro, like \nc{} but I would prefer not to use something like it. In Mathematica, we have the ability to insert non-compiling codes with (* non-compiling text *)

Consider the code: \documentclass[12pt]{book} \usepackage[paperwidth=6.00in,paperheight=9.00in,top=.5in,bottom=.5in,left=.75in,right=.5in]{geometry} \textheight=7.25in \voffset=0.35in \usepackage{lipsum,enumitem} \begin{document} \pagestyle{empty} \begin{enumerate}[label={(\Roman*.)},itemindent=1em,leftmargin=0em] \item \lipsum[12] \item \lipsum[12] \item \lipsum[12] \item \lipsum[12] \item \lipsum[12] \end{enumerate} \end{document} which produces the output: I would like to reduce the width of the enumerate items by say, a factor of .75; however, when I tried embedding the enumeration within a minipage environment, there is no pagebreak. QUESTION: How may I adjust the width of the displayed items in the enumerate environment? Thank you.
