While writing paper, I found that abnormal vertical blank space appears at the bottom of footnotes in the first column of the cas-dc template. Even after replacing the original paper content with other characters, the issue still persists, and the reproducible code provided below is just an example rather than the only scenario that triggers this problem. I am using TeX Live 2026 on the Windows system and compiling documents with pdflatex, and I aim to identify the root cause of this abnormal blank space and find corresponding methods to avoid it. \documentclass[a4paper,fleqn]{cas-dc} \begin{document} \shorttitle{} \title[mode=title]{consequat.

Basically, I have a custom theorem environment from the tcolorbox package, it doesn't admit regular labels, so instead you have to put the label as the second argument and when you want to reference it you need to add a custom preface in front of it, for example in my case I add "teo:". \documentclass[a4paper,10pt, dvipsnames]{article} %\documentclass[a4paper,10pt]{scrartcl} \usepackage[utf8]{inputenc} \usepackage{amsfonts} \usepackage{mathtools} \usepackage{amsmath,amssymb,amsthm} \usepackage{geometry} \usepackage[spanish]{babel} \usepackage{enumerate} \usepackage{hyperref} \usepackage[autostyle=true]{csquotes} \usepackage[breakable,many, listings, skins]{tcolorbox} \tcbuselibrary{theorems} \usepackage{cleveref} \newtcbtheorem [number within=section]% init options {theorem}% name {Teorema}% title {% colback=blue!5, colframe=blue!35!black, fonttitle=\bfseries, breakable , drop shadow , }% options {teo}% prefix \crefname{tcb@cnt@theorem}{\itshape\bfseries{Teorema}}{Teoemas} \begin{document} \begin{theorem}{(Integración por Partes)}{integracion-por-partes} Si $f \in R(\alpha)$ en $[a, b]$, entonces $\alpha \in R(f)$ en $[a, b]$ y se tiene: $$\int_a^b f(x)d\alpha(x) + \int_a^b \alpha(x)df(x) = f(b)\alpha(b) - f(a)\alpha(a)$$ \end{theorem} \cref{teo:integracion-por-partes} \end{document} I managed to add all theorem labels to the list of labels TexStudio recognizes by adding a custom cwl file that basically just says: \begin{theorem}{title}{label}#l And the labels do show up as you can see here: Only problem is, I would like for them to show up with the preface "teo:" so that I don't have to add it manually every time, since it also shows up without it in autocompletion.

I'm new to luadraw and I'm trying to recreate the diagram below: Here is my code so far, and the result: % !TEX TS-program = LuaLaTeX \documentclass{standalone} \usepackage[3d]{luadraw} \begin{document} \begin{luadraw}{name=wedge} local a, b, c = 8, 6, 4 local xmax, ymax, zmax = a+1, b+1, c+1 local g = graph3d:new{ window3d = {0,xmax,0,ymax,0,zmax}, viewdir = {30,60}, size={10,10,0} } local xIntcpt, yIntcpt, zIntcpt = M(a,0,0), M(0,b,0), M(0,0,c) local P = M(4,0,0) local Q = interDD({P,vecJ},{xIntcpt,yIntcpt-xIntcpt}) local R = interDD({P,vecK},{xIntcpt,zIntcpt-xIntcpt}) g:Dscene3d( g:addPolyline({ {Origin,xmax*vecI}, {Origin,ymax*vecJ}, {Origin,zmax*vecK}, }), g:addPolyline( {xIntcpt,yIntcpt,zIntcpt}, {close=true,color="cyan"}), g:addFacet( {P,Q,R}, {color="cyan",opacity=0.5} ), g:addPolyline( {P,Q,R}, {close=true,color="cyan",style="dashed"} ), g:addLabel( "\\(x\\)",P,{pos="NW",dist=0.1}, a,xIntcpt,{pos="NW",dist=0.1}, b,yIntcpt,{pos="N",dist=0.1}, c,zIntcpt,{pos="NW",dist=0.1} ) ) g:Show() \end{luadraw} \end{document} The issue, as you can see, is that the point (0,6,0) is out of frame. I tried increasing ymax, that seems to have no effect. I tried changing the width in the size option, but that only stretches the diagram horizontally. I have tried different viewdir options, but they all cut the diagram off at one edge. I'm sure it's something basic that I'm missing, but I'm too much of a novice to notice. Any clues?

I'm writing a document that must use endnotes (rather than footnotes), and the endnotes must be indexed along with the main text. I'm having trouble with how the endnotes package is manipulating index entry formatting constructs, resulting in duplicate index entries. Importantly, the \string trick given in previous posts about duplicate index entries doesn't seem to work. MWE: \documentclass[letterpaper,11pt]{article} \usepackage{endnotes} \let\footnote=\endnote \usepackage{mhchem} \usepackage{makeidx} \makeindex \begin{document} The bacterium \emph{E. coli}\index{Escherichia coli@\emph{Escherichia coli}} tolerates environments with oxygen\index{dioxygen@dioxygen ($\ce{O2}$)}. This sentence has a note with index entries encoded in exactly the same way as the text above.\footnote{See references for more about \emph{E. coli} \index{Escherichia coli@\emph{Escherichia coli}} and oxygen\index{dioxygen@dioxygen ($\ce{O2}$)}.} This sentence has a note with index entries modified according to the old \texttt{\\string} trick described in Stack Exchange posts from ten years ago. \footnote{See references for more about \emph{E. coli} \index{Escherichia coli@\string\emph{Escherichia coli}} and oxygen \index{dioxygen@dioxygen ($\string\ce{O2}$)}.} \theendnotes \printindex \end{document} This leads to the index file: \indexentry{Escherichia coli@\emph{Escherichia coli}}{1} \indexentry{dioxygen@dioxygen ($\ce{O2}$)}{1} \indexentry{Escherichia coli@\emph {Escherichia coli}}{1} \indexentry{dioxygen@dioxygen ($\ce {O2}$)}{1} \indexentry{Escherichia coli@\string \emph {Escherichia coli}}{1} \indexentry{dioxygen@dioxygen ($\string \ce {O2}$)}{1} Naively inserting identical index entries in the footnotes leads to an extra space after control sequences like \emph and \ce. However, the trick of putting \string in front of each control sequence (which works great in normal \footnote environments, as well as in \caption and the like) breaks here. Looking over endnotes.sty, I'm guessing the problem arises from how it writes out the notes to a temporary file, inserting newlines after each token, and then inserts spaces when it reads it back? Any ideas how to get this working right? Sadly, I don't know enough TeX to redefine \index to strip those spaces, but it would seem like there must be some way?

I’m working on a multi-file LaTeX project in VS Code using latexmk, biblatex (with biber), and nomencl.

I am writing my thesis and I am adding a figure having subfigure. The code is below: \begin{figure} \centering \begin{minipage}{6cm} \centering \includegraphics[width=7cm,height=7cm]{ring_2D_dom.eps} \captionof{subfigure}{Quarter of annulus domain.} \label{3fig:firstring} \end{minipage} \hspace{1.5cm} \begin{minipage}{6cm} \centering \includegraphics[width=7cm,height=7cm]{thick_ring.eps} \captionof{subfigure}{Thick ring shaped domain.} \label{3fig:thick_ring} \end{minipage} \vspace{1cm} \begin{minipage}{6cm} \centering \includegraphics[width=7cm,height=7cm]{igloo.eps} \captionof{subfigure}{Igloo shaped domain.} \label{3fig:second} \end{minipage} \caption{Computational domains.} \label{3fig4} \end{figure} I know I should be using the subfigure command, but after many trials this is the only solution I got to add subfigures without any errors. Now, when I am referring the first subfigure in the text it is displaying Figure 3.0(a) rather than showing Figure 3.1(a). Can anyone help me to get this correct?

I need to align the \closing{} of the letter package with the body of the letter, on the left, while keeping the \signature{} but this code is actually removing the \signature{} from the rendered document: \documentclass[a4paper]{letter} \signature{Your Name} \address{Your Address} \date{\today} % I renew the closing command here, before beginning the document: \renewcommand{\closing}[1]{\par\noindent#1\par} \begin{document} \begin{letter}{Recipient Name \\ Recipient Address} \opening{Dear Sir or Madam,} This is the body of the letter. Lorem ipsum dolor sit amet, consectetur adipiscing elit. Proin gravida augue at eleifend vestibulum. Nullam mollis molestie mi eget viverra. Interdum et malesuada fames ac ante ipsum primis in faucibus. Ut scelerisque dui in eros imperdiet consectetur. Cras venenatis elit nec orci elementum pellentesque. \closing{Sincerely,} \vspace{1cm} \hspace*{0.6\textwidth} \signature{} \end{letter} \end{document} Here's the corresponding result using Texmaker 5.0.3 on Ubuntu 22.04.5:

When using fractions in \polylongdiv, the vertical spacing turns out rather awkward. If no fractions are used for the coefficients, the spacing is fine. I have tried to adjust the vertical spacing using arrayrowsep=..., but without any visible change. Is it possible to adjust this vertical spacing for fractions? \documentclass{article} \usepackage{polynom} \polyset{style=C,div=:,arrayrowsep=1cm} \begin{document} \polylongdiv[arrayrowsep=1cm]{(1/5)x^2-(3/7)x+4/9}{x-1/2} \polylongdiv[arrayrowsep=1cm]{5x^2-5x+6}{x-3} \end{document}

I have a working exercise/solution engine based on that from the tcolorbox documentation and it works perfectly. There is one thing I would like to change if possible. In my MWE, I create three exercises and their corresponding solutions and I also create new autorefnames for their respective counters. The exercises are in two different sections but all the solutions are in a new section and that causes the solution numbers typeset when I cite them with \autoref to reflect the new section, not the sections of the corresponding exercises. In other words, the names of the solutions to Exercise 1.1 and Exercise 2.1 typeset as Solution 3.1 and Solution 3.2 whereas I would like them to be Solution 1.1 and Solution 2.1 respectively even if they are in the third section. I think my question is: can I make a solution's number retain the value of the number of its corresponding exercise even when the solution is in a different section of the document? I have experimented and nothing I have tried works. This is for a larger book project and I can live with the situation but I want to know if my question has a relatively simple answer.

How can I get the actual height available for content on a chapter title page excluding the space for chapter title etc at the top? Some context, I have code that generates latex with an \adjustbox{max totalheight=\textheight} box on a page (so I don't know beforehand whether this will occur on a page with a title or not). \textheight does not factor out the height of the chapter title. Is there some reasonably robust and "correct" way of getting the actual text height available? Minimal example that demonstrates that \textheight is the same on pages with or without a chapter title: \documentclass[a4paper]{book} \usepackage{lipsum} \begin{document} \chapter{A Chapter Title} \lipsum[2] \textbf{Text Height \the\textheight} \\ \lipsum[2] \newpage \lipsum[2] \textbf{Text Height \the\textheight} \\ \lipsum[2] \end{document}

Idk how to really describe this, but notice how the 1 sits at the bottom of the first image and the 2 sits at the top. I've used an enumerate environment here and I also used columns, because I just don't want to waste all this empty space and make 2 half slides instead of 1 full one. Here's a minimal work example: \documentclass{beamer} \begin{document} \begin{frame} \begin{columns} \begin{column}{0.4 \textwidth} \begin{enumerate} \item \includegraphics[scale = 0.2]{picture 1} \item \includegraphics[scale = 0.2]{picture 2} \end{enumerate} \end{column} \hfill \begin{column}{0.4 \textwidth} Why does it work? \begin{itemize} \item \end{itemize} \end{column} \end{columns} \end{frame} \end{document} Also here's picture 1 and picture 2:

I am editing a paper with about 30 authors divided into groups, each responsible for one or two sections. I have a master file with header information (title, abstract, etc.) and trailer information, author list, acknowledgements, bibliography. In between, each section is incorporated with \Secin{<file>} directives (see below). In the header, before the \begin{document} is a \input{Include} statement. The file Include.tex contains a \includeonly{} line, and a \newcommand{} line that defines \Secin{} to use either \input{} or \include{}. This is necessary because the document is an article, not a book and has \sections{} rather than \chapters{} and when processing the whole paper, \inputs are needed to avoid page breaks. I have a shell script that takes as an argument a digit, N, 1 - 6 to process group N's section(s). It renames the existing output pdf file, copies the group's IncludeN.tex file to Include.tex, runs pdflatex on the primary file, renames the resulting pdf file adding an N before the .pdf and copies Include00.tex, the default (which uses \input{} and has no \includeonly{}) to Include.tex and renames the old pdf file back to its original name. At each iteration in the editing, I send the authors in each group, their section(s) as pdf and LaTeX. Some are LaTex users and can edit their source. For others, I make the changes based on their inputs. So far, so good, but when I added labels to each section to allow cross referencing, strange things happened. When I process the whole document using the default Input.tex, and the references stabilize, I find \newlabel{}s in the primary aux file for all labels in all sections. There are no aux files for the sections because these runs are being done with \input{}s. The first time, I ran my script to select a single group's section, I got a "labels may have changed, rerun" message. Fair enough, but when I rerun, I get an undefined label message for a label defined in another section, but referenced in one I am processing. At this point, the primary aux file has no \newlabel for the label I am referencing and there is no aux file for the other sections. My solution is to define the Include0.tex file (For the group of all authors) to set the input method to \include{} but to omit an \includeonly{} directive. When I run this, I get a pdf for the entire document with each section starting on a new page and the per section .aux files. The default Include.tex file is left with the \Secin{} command defined as \input{} so the pdf is in the publication form with no forced page breaks if I run pdflatex directly on the primary input file. I figured out what was going on while writing the question, and this works, but it seems that there ought to be a better way. When \includeonly is used on a chaptered document or any one in which each input file's output should start on a new page, the \input{} and \include{} results are the same. Is there any way to suppress the page break on \include{}?

I have (finally!) been able to input custom alt text for a non-standard symbol, to be used as a mathematical operator, which is also actually read correctly by a screen reader (NVDA 2026.1beta6, I believe, with Adobe Acrobat). A working example (with some non-working attempts commented out) is below. I'm trying to incorporate this example into some guidelines for submitting accessible mathematics thesis documents based on the new (in progress!) LaTeX Tagging (PDF 2.0 UA/2) capabilities. My question: does anyone know if this way of manually giving a "new" symbol (or existing symbol) screen readable alt text is likely to persist, or are there other alternatives to doing this that (1) work, and (2) are more likely to become the standard approach in the next year or two?

I would like to use Initials in a nice poetry book and need for German Umlaute (Ä Ö Ü) those designs.

In one particular case, I wanted to use an animation from the animate package and also include buttons from the Acrotex package aebpro, or eforms (from the tlcontrib repository with TeX Live). When I try this, the buttons are no longer visible. If you know where they are, you can click on them with the mouse in the PDF. To find their location, I placed the buttons in a \fbox. All actions (for example, JS code) are still executed, even if the buttons are not visible. I tried using JavaScript to trigger the buttons’ appearance. Interestingly, this only works on the first page. The buttons then become visible again. But not on the second and subsequent pages. If anyone knows how to make the buttons remain visible on subsequent pages, I would be very grateful for any advice. \documentclass{article} %% compile with LaTeX + dvips + ps2pdf %% or with LaTeX + dvips + distiller \usepackage[% driver=dvips, eforms={useui}, uselayers, ]{aeb_pro} \usepackage{animate} %============== comment this code ======================== \begin{insDLJS}{refreshButtons}{Refresh button appearances} function refreshButtonAppearances() { try { for (var i=0; i<this.numFields; i++) { var nm = this.getNthFieldName(i); var f = this.getField(nm); if (f && f.type === "button") { // Caption "neu setzen" triggert oft die Appearance-Erzeugung var cap = f.buttonGetCaption(); f.buttonSetCaption(cap); } } } catch (e) {} } refreshButtonAppearances(); \end{insDLJS} %========================================================== \begin{document} \fbox{\pushButton[\CA{A}\A{\JS{%app.alert("You chose A"); toggleSetThisLayer("l1");}}]{I}{8cm}{1cm}}% \xBld{l1} Text on layer l1 \eBld \begin{animateinline}[% controls, begin={\begin{minipage}[t]{10cm}}, end={\rule[-0.5cm]{0pt}{2cm}\end{minipage}}, ]{2}% 2 images/s \multiframe{5}{nA=0+1}{% \rule{\nA cm}{15pt}Text } \end{animateinline} \bigskip \fbox{\pushButton[\CA{B}\A{\JS{app.alert("You chose B");}}]{II}{8cm}{1cm}}% \newpage Text on side 2 \fbox{\pushButton[\CA{C}\A{\JS{app.alert("You chose C");}}]{III}{8cm}{1cm}}% end \newpage Text on side 3 \fbox{\pushButton[\CA{D}\A{\JS{app.alert("You chose D");}}]{IV}{8cm}{1cm}}% end \end{document}

I've seen assertions (some going back a few years) that the Adobe Acrobat accessibility checker falsely gives failures for some list tagging structures. The automatically generated Table of Contents is one particular example. Is this true for the following minimal example, compiled using the current lualatex, or is there actually something wrong with the tagging structure? If passing the Adobe checker were to be required by your institution, is there a way to somehow force a ToC tagging structure that would pass the Adobe accessibility checker? \DocumentMetadata{ lang=en, tagging=on, testphase={latest,firstaid}, pdfversion=2.0, pdfstandard={ua-2,a-4f}, uncompress } \title{Minimal Example} \documentclass{report} \usepackage[linktoc=none,pdfusetitle]{hyperref} %linktoc = section, page, both, or none \begin{document} \tableofcontents \chapter{One} \section{Two} \end{document}

I need to make a decision-tree that goes sideway, and if possible I do not want to use a diamond for the "decision" node because I need to fit a lot of text in the decision node. I have sent along a hacky sample to show you want I have mind. I wonder if there are existing latex package that could automate the making of such decision trees? i.e. I do not have to manually position each node/arrow. Bonus request: I would like to have rounded corners for the rectangular boxes. Thanks for your help.

I have a large set of images that I reuse in a book. They all have different bottom crop and so far I have used the macro \image{21}{002} to show image 002.pdf with a 21 bottom crop. I would like to use a macro that, based on the image ID (e.g. 002), looks up the corresponding value (21) and applies the crop consistently. I have tried \documentclass[11pt]{book} \usepackage{graphicx} \usepackage{pgf,tikz,pgfplots} \pgfplotsset{compat=1.15} \def\image#1#2{ \medskip\par\nobreak \centerline{ \begin{tikzpicture} \draw[below right] (0, 0) node[inner sep=0] {\fbox{\includegraphics[trim={25 #1 25 10},clip]{graphics/chorales/#2.pdf}}}; \end{tikzpicture} } } \def\imageAuto#1{ \medskip\par\nobreak \def\cropvalue{10} \ifnum #1=002 \def\cropvalue{21} \fi \centerline{ \begin{tikzpicture} \draw[below right] (0, 0) node[inner sep=0] {\fbox{\includegraphics[trim={25 \cropvalue 25 10},clip]{graphics/chorales/#1.pdf}}};}; \end{tikzpicture} } \begin{document} \image{21}{002} \imageAuto{002} \end{document} with \imageAuto a ‘basic’ solution for a look-up-function (with the default 10), but it does not work. Is there a (better) solution to my problem? PS. The reason for using TikZ is that I need to place text objects on the image, but I have removed those lines for clarity in this post.

I need all binomial coefficients for n=1..100 and k=1..100 several times, so I wrote a code with xint: \xintdefvar BinomialArray = ndseq(binomial(n,k), n=1..100; k=1..100); \xintdeffunc abinomial(n,k):=BinomialArray[n-1,k-1]; I measured out for that: ******************************************** *** TOTAL COMPILATION TIME REPORT: *** (l3benchmark) + TOC: 2.27 s ******************************************** This is OK, but I asked myself: Is there any way I can store the array (in a file?) so that it doesn't have to be recalculated on every new run? \documentclass[paper=a5, paper=landscape]{scrarticle} \usepackage[margin=10mm]{geometry} \usepackage{xintexpr} \usepackage{amsmath} \begin{document} \xintdefvar BinomialArray = ndseq(binomial(n,k), n=1..100; k=1..100); \xintdeffunc abinomial(n,k):=BinomialArray[n-1,k-1]; %Test: \xinteval{BinomialArray[100-1,50-1]} works Test: $\dbinom{100}{50}=\xinteval{abinomial(100, 50)}$ % Show complete array - on your own risk :() %\newpage %\begingroup %\tiny %BinomialArray = \xintthealign\xintexpr BinomialArray\relax %\endgroup \end{document}

Based on this answer, I am using a latex preamble file to customize a bulleted list in a PDF created by pandoc from a github-flavored markdown source file. I would like to also customize the vertical space between list items. I would expect adding a line ,itemsep = 1cm would do that, but it has no effect. The preamble file is % Source - https://tex.stackexchange.com/a/760974 % Posted by jlab % Retrieved 2026-03-20, License - CC BY-SA 4.0 \usepackage{enumitem} \newcommand{\signatureline}{\rule[-2pt]{2cm}{1pt}} \setlist[itemize]{ ,label = \signatureline ,labelindent = \parindent ,labelsep = 2pt ,labelwidth = 2cm ,leftmargin = * }

As what my knowledge could tell, It's possible to create a triangle with only 2 coordinates to make real angles to be exact, and using path to create long rays and naming the intersection of those rays and finally connect them with \draw. MWE: \documentclass[tikz, border=10pt]{standalone} \usepackage{siunitx} \usetikzlibrary{intersections} \begin{document} \begin{tikzpicture}[scale=2] \clip (0,0) rectangle (5,2.1); \coordinate (A) at (0,0); \coordinate (C) at (5,0); \path[name path=AB] (A) -- ++(37:4); \path[name path=BC] (C) -- ++(137:4); \path[name intersections={of=AB and BC, by=B}]; \draw[thick] (A) -- (B) -- (C) -- cycle; \end{tikzpicture} \end{document} There is a noticable difference if I comment \clip in the 6th line. Without it, it's going to be a white space... It's impractical to calculate the height of the object if I make another drawing with more complicated shape. So, is it possible to autocrop the exceeding lines? What I meant by exceeding lines is like the cyan lines in the figure below. It's because they contribute to white space if I change \draw to \path: So, if possible, I want TikZ to automate cropping the intersection, in other words, getting rid of those exceeding lines without estimating like how much the height is (would consume loads of time if I make other complicated figures with intersections). To illustrate what I actually want, roughly I want something like this: Yes, I deliberately cropped it poorly to give an example as to what it shows if I gave them an incorrect clipping, which I wish I didn't need to clip it, but instead, I wish TikZ only read the intersection point and two given coordinates to draw.

I have some code here that calculates the functions \bdceval{\n}{\p}{\k}, row by row, for fixed \n and \k values ​​and values ​​p from a list \def\pList{0.1, 1/6, 0.25, 0.3, 0.4, 0.5}. It works and is correct. But I'm wondering: Is this well-designed in terms of performance? I can only manage to implement \makePListRow{\n}{\k} with two commands. \documentclass{article} \usepackage{tikz} \usepackage{xintexpr} \def\pList{0.1, 1/6, 0.25, 0.3, 0.4, 0.5} % Function: \xintNewFloatExpr{\bdceval}[3]{add(binomial(#1,v)*#2^v*(1-#2)^(#1-v), v=0..#3)} % Commands for List: \newcommand{\myRowMapper}[1]{\xintRound{4}{\bdceval{\n}{#1}{\k}}} \NewExpandableDocumentCommand{\makePListRow}{mm}{% \xintListWithSep{, }{% \xintApply{\myRowMapper}{\xintCSVtoList{\pList}}% }% } \begin{document} \foreach \n in {2,3,7}{% \foreach \k in {0,...,\n}{% \n, \k, \makePListRow{\n}{\k} \par }% } \end{document}

I am building an accessible PDF using tagpdf as follows: \DocumentMetadata{ lang = fr-FR, pdfversion = 2.0, pdfstandard = ua-2, pdfstandard = a-4f, %or a-4 tagging = on, tagging-setup={math/setup=mathml-SE} } \documentclass[a4paper,11pt]{article} % Page layout \usepackage[margin=2.5cm]{geometry} \usepackage{lipsum} \usepackage{pdfpages} % General information \author[]{YamiOmar88} \title{Some Title} \date{} % remove semantic paragraphs: \AssignTaggingSocketPlug{para/semantic/begin}{noop} \AssignTaggingSocketPlug{para/semantic/end}{noop} \begin{document} \maketitle \section*{Some Section} \lipsum[1] \clearpage % --- Poster pages (NOT accessible, marked as artifacts) --- \tagstructbegin{tag=Artifact, alt={Tableau de bord non accessible}} \includepdf[pages=1, fitpaper=true, artifact]{example-image.pdf} \includepdf[pages=1, fitpaper=true, artifact]{example-image.pdf} \tagstructend \end{document} As it can be seen, I add pages using \includepdf. For this example purpose, I'm adding the example-image.pdf as a page so the code can be compiled without external files. The <Artifact> I declare shows as a <Private> tag inside the <Sect> tag. But in this particular file I'm working, it would make more sense for it to be at the same level as the <Sect> tag instead of inside it. Is this possible? In other words, I want this: <Document> <p> <p> <Sect> <H1> <p> <Private> instead of this: <Document> <p> <p> <Sect> <H1> <p> <Private> Note: The code is compiled with LuaLaTeX using MiKTeX 26.2. My LaTeX version is LaTeX2e <2025-11-01>, L3 programming layer <2026-01-19>.

I wish to draw something like this: I can draw the two lines, though it is difficult to be precise. However I don't know what to do next as for the dashed line and the arrow line. The dashed lines are perpendicular to MK and JL, but the arrow line are parallel to those lines. And the difficult part is connecting the dashed line with the arrow line.

It seems (or is apparently) that thickness of lines is hard coded. Consequently when drawing a line, the use for example of scale=2 only makes the line longer and its thickness is not changed, see MWE below: \documentclass[margin=3mm, varwidth]{standalone} \usepackage{tikz} \usetikzlibrary{arrows.meta} \tikzset{LA/.style = {-Straight Barb, line width=1mm}} \begin{document} \begin{tikzpicture} \draw[LA] (0,0) -- ++ (2,0); \end{tikzpicture} \begin{tikzpicture}[scale=2] \draw[LA] (0,0) -- ++ (2,0); \end{tikzpicture} \end{document} Is there some trick by which the thickness of the line will also be scaled? The best way would be as option of the line style, which will have effect just on this particular line. My quick search on this site so far didn't give me any suggestion ...
