Using TeX Live 2023/Debian. I am creating a document in single column format, which will contain many examples comparing code versus graphical patching representations of the same concepts. If every such example is arranged vertically, it will waste a lot of vertical space, so whenever possible, I would like to place the code on the left and a screenshot of the graphical patcher on the right, within the figure, while the rest of the page is single column. I did a couple of searches and I can only find answers about placing a single column figure into a multiple column document (e.g. Placing a figure in one-column within a two-column document). While I can understand why that's a popular requirement, it's the opposite of what I want to do.

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:

The following tabularray's tabular is as expected: the extendable X column type makes its width exactly equal to \linewidth: \documentclass[draft]{article} \usepackage{tabularray} \begin{document} \noindent \begin{tblr}{ vlines, colspec={ l l X }, % cell{1}{1} = {c=2}{}, } Foo & bar & baz \\ \end{tblr} \end{document} But, as soon as the the first two cells (of the single row) are merged (uncomment cell{1}{1} = {c=2}{}), the tabular's width exceeds \linewidth: How to circumvent this trouble?

Naturally i want this to add the next comment after it detects the next y. My current progress is: \documentclass{article} \usepackage{amsmath} \makeatletter \newcommand{\hbrace}[1]{% \mathop{% \vtop{% \m@th% \ialign{% ##\crcr% $\hfil\displaystyle{#1}\hfil$% \crcr% \noalign{\kern 1pt \nointerlineskip }% \negthinspace \vrule height 3pt width .3pt% \leaders\hrule height 1.4pt depth -1pt \hfill% \vrule height 3pt width .3pt \negthinspace \crcr% \noalign {\kern 1pt}% }% }% }\limits% } \makeatother \begin{document} \begin{center} $\hbrace{\text{heyyyyy}}$ \end{center} \end{document}

How to set a really compact latex style? bibliographystyle{abbrv} which shortens names but this style lists editors, location and other things that use more space than necessary

I have has this \newcommand{\Vis}{\boldsymbol{!}} for a bold and fat exclamation mark to serve as an operator. Some advised me to use \newcommand{\Avail}{\mathord{\raisebox{0.2ex}{\rotatebox{180}{$\boldsymbol{!}$}}}} for the dual operator with an upside-down exclamation mark. But the latter definition generated stability problems or something like that, in the document. Is there a more stable manner to obtain the dual operators which I want, which I may put into my preamble, which is as follows? \documentclass[english,aspectratio=169]{beamer} % ========================= % LuaLaTeX font setup % ========================= \usepackage{fontspec} % ========================= % Graphics % ========================= \usepackage{tikz} % Serif text font (safe, neutral) \setmainfont{Latin Modern Roman} % Math font %\setmathfont{Latin Modern Math} % ========================= % Language and typography % ========================= \usepackage[english]{babel} \babelprovide[import]{arabic} \babelprovide[import]{persian} \usepackage{luabidi} \babelfont[arabic]{rm}{Amiri} \babelfont[persian]{rm}{Amiri} \usepackage{microtype} \usepackage{url} % ========================= % Mathematics % ========================= \usepackage{amsmath} % Also has \boldsymbol \usepackage{mathtools} %========================== \usepackage{bm} % For \bm (often preferred to \boldsymbol %under \usepackage{amsmath} for better spacing) %========================== % ========================= % UiO Beamer theme % ========================= \makeatletter\let\arrowvert\@undefined\makeatother%To avoid expand LaTeX Error: Command `\arrowvert' already defined.‪/usr/local/texlive/2023/texmf-dist/tex/latex/newtx/newtxmath.sty, 878‬ \usefonttheme{professionalfonts} \usetheme{UiO} \urlstyle{sf} % -------------------------------------------------------- %Graphics (required for \rotatebox) %--------------------------------------------------------- \usepackage{graphicx} % ========================= % Semantic macros % ========================= \newcommand{\defeq}{\mathrel{\vcentcolon=}} \newcommand{\Vis}{\boldsymbol{!}} \newcommand{\Avail}{\mathord{\raisebox{0.2ex}{\rotatebox{180}{$\boldsymbol{!}$}}}} \newcommand{\Tr}{\mathsf{Tr}} \newcommand{\Aut}{\mathsf{AE}} % ========================== % Bend supports %=========================== \newcommand{\godel}[2][]{% \mspace{1\medmuskip}% \vphantom{#2}% \begin{tikzpicture}[baseline=(M.south)] \node[inner ysep=0pt,inner xsep=4pt](M){\smash[b]{$#2\mathstrut$}}; \draw[rounded corners=.5mm,#1]([xshift=-1mm]M.south east)--(M.south east)--++(0,.14); \draw[rounded corners=.5mm,#1]([xshift=1mm]M.south west)--(M.south west)--++(0,.14); \end{tikzpicture}% \mspace{1\medmuskip}% } % ========================= % Bibliography matters % ========================= \usepackage[ backend=biber, style=authoryear, maxbibnames=3, giveninits=true ]{biblatex} \renewbibmacro*{in:}{} \addbibresource{lassiclib.bib} % ========================= % Front matter % ========================= \begin{document} $\Avail{\godel{A}}\defeq$ just if $\vdash A\wedge \ldots$ Compare $!$ with $\Avail{~}$ \end{document}

I'm typesetting a book with 11 chapters and about 90 sections, and each section file also has a separate file of exercises. I'd like to have flexible options for typesetting just one chapter, or one section, or just exercises, etc., with the nice features that \include offers for preserving page numbers, section numbers, etc. I've thought of a way to do this with families of include and includeonly. Something like this \documentclass{book} \newenvironment{includechapter}[1] {} {} \newcommand{\includesection}[1]{} \newcommand{\includeexercises}[1]{} % this command, by itself, would cause only chapter 2 to typeset, % including the files sec2p1, exs2p1, sec2p2, exs2p2. Nothing from % chapter2 would typeset. % \includechapteronly{chapter2} % this command, by itself, would prevent any other sections to % typeset. % \includesectiononly{sec1p2} % this command, by itself, would prevent any other exercises to % typeset. % \includeexercises{exs1p2} % these three commands, would turn off chapter2, turn off all % sections, and turn on only one set of exercises % \includechapteronly{chapter1} % \includesectiononly{} % \includeexercises{exs1p2} \newif\ifAnyPart \makeatletter \if@chapterpartsw \ifAnyParttrue\fi \if@sectionpartsw \ifAnyParttrue\fi \if@exercisespartsw \ifAnyParttrue\fi \makeatother \begin{document} \ifAnyPart\else \tableofcontents \fi \begin{includechapter}{chapter1} % file chapter1 has \chapter command \includesection{sec1p1} % has \section command \includeexercises{exs1p1} % has \section*{Section\thesection Exercises} \includesection{sec1p2} \includeexercises{exs1p2} \end{includechapter} \begin{includechapter}{chapter2} \includesection{sec2p1} \includeexercises{exs2p1} \includesection{sec2p2} \includeexercises{exs2p2} \end{includechapter} \ifAnyPart\else \printindex \fi \end{document} I think I might be able to figure out how to copy code from \include and \includeonly and make three different versions of it, three different lists to check, etc. But I'm sure I'll make some mistakes. Maybe other people will know how to do this, or pitfalls I should look out for, or that there's some other way to do it. Or (worst!) that it's not really possible.

After updating MiKTeX (verified in MiKTeX Console, 2026-01-12), I encountered the following issue: Minimal Working Example (MNWE): \documentclass{scrbook} \usepackage[czech]{babel} \begin{document} Test with babel \end{document} Error log: ! LaTeX hooks Error: Generic hooks cannot be added to '@startsection'. It seems the problem is related to the combination of: The scrbook class (KOMA-Script) The babel package with czech option The new LaTeX hooks system (2020+) Possibly the xpatch package Question: How can I resolve this conflict? Is there a recommended approach or workaround to use scrbook together with babel (Czech) without triggering this error?

I have a tikz graphic that generates fine when I inline the code. My document has a lot of graphics so I've been placing each tikz in its own file and importing when needed. Thus, when I placed this graphic in its own file pdf generation would fail with a TeX capacity exceeded error. I don't understand why. Here's the code that works: \documentclass{article} % LTeX: enabled=false \usepackage{tikz} \begin{document} \begin{figure} \begin{tikzpicture}[inner sep=0pt, outer sep=0pt] \definecolor{bodyOline}{RGB}{151,154,155} \definecolor{bodyFill}{RGB}{242,242,242} \definecolor{ecgGreen}{RGB}{4,203,153} \path[draw=bodyOline,fill=bodyFill] (6.1343, 11.9492).. controls (5.8796, 11.88) and (5.7804, 11.7586) ..

Could someone please help me explain why am I getting the following errors in my .tex file, and also how to fix it? I am trying to construct a scatterplot using Tikz.

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.

I can already place pieces, arrows, and coordinates on the chessboard. What I’d like to do now is to highlight a specific rank and file by: drawing a horizontal line across a rank (e.g. rank 5), drawing a vertical line along a file (e.g. file d), and drawing rectangular boxes around the corresponding coordinate labels (5 and d), as shown in the image below. Is there a standard or recommended way to do this using common chess diagram tools (e.g. LaTeX chessboard / xskak with TikZ overlays, or other libraries)? Thanks a lot

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)

mwe.tex: %\DocumentMetadata{lang=en} \documentclass{scrartcl} \usepackage[hidelinks]{hyperref} \begin{document} \tableofcontents \clearpage \section{My first section} \end{document} I'm now running: latexmk -lualatex mwe.tex This produces mwe.pdf, pdf version 1.5. If I open the file in Adobe Acrobat, the section title My first section in the TOC is clickable so that I can directly jump to the section text. Now I'm uncommenting the first line and compile the document again. The compilation run now produces PDF version 2.0. Unfortunately, in the pdf produced, the section title in the TOC is not clickable any more. What do I have to add (\hypersetup !?) to make the TOC title clickable again? Thanks for our help!

I want to force a page break within a longtblr environment. The documentation states that this can be done using the \pagebreak command; however, when I do so, the contfoot-text is not applied. How can I force a page break while still preserving the contfoot-text? The following MWE demonstrates my exact use case and explains the motivation for enforcing a page break. \documentclass[a5paper]{article} \usepackage[margin=2in, includeheadfoot]{geometry} \usepackage[table]{xcolor} \usepackage{tabularray} \DeclareTblrTemplate{contfoot-text}{mystyle}{\small\itshape Continued on next page\textellipsis} \SetTblrTemplate{contfoot-text}{mystyle} \DeclareTblrTemplate{conthead-text}{mystyle}{(\emph{Continued})} \SetTblrTemplate{conthead-text}{mystyle} \begin{document} \begin{longtblr} [ caption={Long table} ] { colspec = {X[l,m] Q[l,m,0.5\linewidth]}, row{1} = {c,m,bg=gray,font=\bfseries}, column{1} = {font=\bfseries}, rowhead = {1}, hlines, vlines, } A & B \\ \SetCell[r=10]{l,m}Merged 1 & R1\\ & R2\\ & R3\\ & R4\\ & R5\\ & R6\\ & R7\\ & R8\\ & R9\\ & R10\\\pagebreak \SetCell[r=10]{l,m}Merged 2 & R1\\ & R2\\ & R3\\ & R4\\ & R5\\ & R6\\ & R7\\ & R8\\ & R9\\ & R10 \end{longtblr} \end{document} A hack is given in this answer. However, I will wait for any better alternative.

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};

In certain contexts (italian schools) an ideal DC voltage source is represented by the symbol in this circuit: \documentclass{standalone} \usepackage{circuitikz} \begin{document} \begin{circuitikz} \draw (0,0) to[V,a^=V1,name=VS] (0,4); \node[above left,inner sep=1pt] at (VS.e) {$+$}; \draw (0,0) to[V,a=V2,name=VS] (4,0); \node[above right,inner sep=1pt] at (VS.e) {$+$}; \draw (4,4) to[V,a=V3,name=VS] (0,4); \node[below left,inner sep=1pt] at (VS.e) {$+$}; \draw (4,4) to[V,a^=V4,name=VS] (4,0); \node[below right,inner sep=1pt] at (VS.e) {$+$}; \end{circuitikz} \end{document} This is the symbol I want. Unfortunately, drawing circuits like this is rather cumbersome, so I’m wondering whether it would be possible to define a CircuiTikz style or a custom component that produces the symbol in a more natural way. I’m not a TikZ expert, and I struggle with the part of the documentation that explains how to create new components. I’m aware of existing questions such as: Adding a plus sign in a circuit diagram Including +/- signs to battery in Circuitikz But the answers there didn't help me. I also had no luck with AI tools, so I’m hoping someone with more experience in CircuiTikz and TikZ can offer some guidance.

If I use color=white, the resistor R wouldn't be visible unless I added a colored background. Out of theoretical interest: Is there a way to pass the resistor with something like draw=none, so that it isn't drawn? (The rest should be drawn as before.) \documentclass[margin=5pt, multi=circuitikz]{standalone} \usepackage{circuitikz} \usetikzlibrary{backgrounds} \begin{document} \begin{circuitikz}[european resistors, background rectangle/.style={draw=none, fill=gray!25, rounded corners}, show background rectangle, ] \draw[] (0,0) to[L=L] (2,0) to[R=R](4,0); \draw[yshift=-12mm] (0,0) to[L=L] (2,0) to[R=R, color=white](4,0); \end{circuitikz} \end{document}

When using TexStudio 4.9.1, which I today have downloaded and installed, there is a strange behaviour when compling with LuaLaTeX. I installed the newest version, since this behaviour has been found the foremost version 4.8.7. Klicking in the menu LuaLteX, compling is starting with pdfLaTex and runs after that lualatex, but gives me an error that LuaLaTex is needed in my source. My source seems correct, since a small MWE works well with LuaLaTeX compiling. I have checked the run settings in the menu, but they are correct, as usual. Does anybody know what can be wrong? And how to fix this?

This is an illustration why one shall not code late at night. Thank you for the ones who helped me. The application pythontex is very important for me, it is still maintained but activity became low a bit so you cannot get quick solution. So I ask for a quick fix. For python 3 it seems to be a wrapper around pythontex3.py. As python changes, the original pythontex3.py needs more and more patches. Don't be shocked, I just overwrote the original by a script. Now i found out that this is not state of the art. I need not patch directly in texmf-dist but in texmf-local. Ok, I patched some packages also and this seems to work. But with pythontex it does not. Still the original pythontex3.py in texmf-dist is used although the one in texmf-local is present also. For packages texmf-local takes priority over texmf-dist. 22:25 $ which pythontex /usr/local/texlive/2025/bin/x86_64-linux/pythontex so you can see i use linux x86_64. But for python scripts I cannot figure out the mechanism that determine the one that it is used. Please help. I want to solve my problem but also understand the techniques.

setup: I wanted to make all my sections and subsections without numbers showing on the left side of each entry. So I changed to using the star version and with manually entering each section or subsection into the main toc. But now I find that only the main TOC is created, but local toc at top of each section is missing. This happens with splitting or no splitting. Removing the star version of sectioning, the local TOC shows up again as expected. Here is a MWE \documentclass[12pt]{article} \begin{document} \ifdefined\HCode \Configure{tableofcontents*}{section} \TocAt{section,subsection} \else \tableofcontents \fi \section*{section 1} \addcontentsline{toc}{section}{section 1}% text \subsection*{subsection 1} \addcontentsline{toc}{subsection}{subsection 1}% text \subsection*{subsection 2} \addcontentsline{toc}{subsection}{subsection 2}% text \end{document} Compiled with make4ht -ulm default -a debug C.tex 'mathjax,htm' Gives this Now see what happens when I change back to normal sectioning (i.e. no star) \documentclass[12pt]{article} \begin{document} \ifdefined\HCode \Configure{tableofcontents*}{section} \TocAt{section,subsection} \else \tableofcontents \fi \section{section 1} text \subsection{subsection 1} text \subsection{subsection 2} text \end{document} Compiled using same command gives I expected local TOC to show up in both cases. Is there a workaround? reference https://puszcza.gnu.org.ua/bugs/index.php?667 Update on a problem found I found a problem with the solution given below. Even though the local TOC does show OK now with star version, but when using splitting, and clicking on a section (which is now is on separate web page), the page opens in wrong location and way down the page. So one has to scroll back to top of the page in order to see the local TOC. When not using starred version of sections, this does not happen. The new page opens near the top and one can see the local TOC. Here is an example showing the problem \documentclass[12pt]{article} \usepackage{lipsum} \begin{document} \ifdefined\HCode \Configure{tableofcontents*}{section} \TocAt{likesection,subsection} %notice, change to likesection \else \tableofcontents \fi \section*{section 1} \addcontentsline{toc}{section}{section 1}% \lipsum[1-5] \subsection*{subsection 1} \addcontentsline{toc}{subsection}{subsection 1}% \lipsum[1] \subsection*{subsection 2} \addcontentsline{toc}{subsection}{subsection 2}% \lipsum[1] \end{document} Compiled using make4ht -ulm default -a debug C.tex 'mathjax,htm,2' Now, opening the file C.htm and then clicking on the section link at the top, the new page shows as the following So now one has to manually scroll way back to the top see the Toc. The above is how the page opens. Tried it on brave, edge and firefox. Now, if I change back to non-star version \documentclass[12pt]{article} \usepackage{lipsum} \begin{document} \ifdefined\HCode \Configure{tableofcontents*}{section} \TocAt{section,subsection} \else \tableofcontents \fi \section{section 1} \lipsum[1-5] \subsection{subsection 1} \lipsum[1] \subsection{subsection 2} \lipsum[1] \end{document} and compile again using same command, this is how the split page opens The local TOC shows and the new page (since using split 2) opens near the top as one would expect. This makes the star version not usable really, since new pages open at wrong location. One should not have to scroll up each time when opening new page to go to the top and to see the TOC. Is there a workaround to make the page opens at top like to the non star version? If not, then I would not be able to use the star version with tex4ht.

I'd like to move the letter H below so it's at a midline height in between the two equations, please. Here's a MWE. \documentclass{article} \usepackage{amsmath} \begin{document} \begin{equation*} \left.\begin{matrix} \frac{x-h}{a}=\sec\theta\Rightarrow x-h=a\sec\theta\Rightarrow x=a\sec\theta+h \\ \frac{y-k}{b}=\tan\theta\Rightarrow y-k=b\tan\theta\Rightarrow y=b\tan\theta+k \end{matrix}\right\}\Rightarrow \mbox{\Huge$\mathcal{H}$:} \begin{matrix} x=a\sec\theta+h \\ y=b\tan\theta+k \end{matrix} \end{equation*} \end{document} This code produces the equations system thus:

I have the following code: \documentclass[margin=5pt]{standalone} \usepackage{circuitikz} \begin{document} \begin{circuitikz}[european] \ctikzset{voltage=raised}%<- \draw (0,0) -- ++(1,0) to[R=R,label distance=3pt, v=$\mathrm{u_R}$] ++(0,+3) -- ++(-1,0); \end{circuitikz} \end{document} However, I want the "+" and "-" to get closer with "u_R"(that is: shift "+" up and shift "-" down), I have tried shift and label distance and voltage/distance from node, but all failed, because they justs tweak the distance between the wire. It's hard for me to dig it out from the manual, is that exists elegant method?
