I can not find the LaTeX command for the following symbol:  Anyone can help? It is an &quot;X&quot; with an horizontal line. And I need also the command for:
I know what my symbol or character looks like, but I don't know what the command is or which math alphabet it came from. How do I go about finding this out?
I am asking this question from an educational/hacking point of view, (I wouldn't really want to code like this).  Is it possible to implement a while loop only using C preprocessor directives. I understand that macros cannot be expanded recursively, so how would this be accomplished? Auto generate an Index Is there any way to auto-gererate an index for the makeidx package? I've written ~270 pages and didn't think of adding \index{} everywhere.  Do I really need to go over everything and add \index{}? Dryer Outlet - 4 prong to 3 prong Our new dryer has 3 prongs vs. 4. We are changing to the new 3 prong dryer outlet, but want to make sure we are grounding. The wires coming from the wall our white, red &amp; black - the the copper wire. Do I need to ground it?? Thank you! Molly A continuation of .  I'm fighting a page-limit in a single-column layout and I need to put a Figure and a Table side-by-side and provide them with independent captions. However, the style guide for the publishers (LNCS) wants Figure captions below and Table captions above (probably something to do with ).   =======================================================  If I adapt @lockstep's floatrow example from  accordingly to have a Table caption above ...  \documentclass{article}  \usepackage{floatrow} % Table float box with bottom caption, box width adjusted to content  %% ********************************** %% just adding \captop to original example %% ********************************** \newfloatcommand{capbtabbox}{table}[\captop][\FBwidth]  \usepackage{blindtext}   \begin{document}  \blindtext  \begin{figure} \begin{floatrow} \ffigbox{%   \rule{3cm}{3cm}% }{%   \caption{A figure}% } \capbtabbox{%   \begin{tabular}{cc} \hline   Author &amp; Title \\ \hline   Knuth &amp; The \TeX book \\   Lamport &amp; \LaTeX \\ \hline   Knuth &amp; The \TeX book \\   Lamport &amp; \LaTeX \\ \hline   Knuth &amp; The \TeX book \\   Lamport &amp; \LaTeX \\ \hline   \end{tabular} }{%   \caption{A table}% } \end{floatrow} \end{figure}  \end{document}   =======================================================  The problem becomes clear ...    =======================================================  The floatrow doesn't correctly line up the Table and Caption. I reluctantly tried to use vspace to solve the problem, but it didn't work out.  Any suggestions on how to get these two to align? I'm happy to accept any alignment that ensures that the Table and Figure fit within the same "box".  (A similar-ish question was , but specific for subfig and with a very localised problem it seems.) Show vote counts on activity>comments page It would be helpful to show vote counts on the activity > comments page, and also allow sorting by votes.  This would make it easy to see what comments other people thought were valuable or at least amusing. Term for a person who can read but cannot write I'm looking for a term to accurately describe a person who can only read but cannot write. While I'm primarily concerned with people who have never learned to write, I would also be interested in any additional terms used to represent people who have lost the ability to write as a result of disuse.  Both illiterate and unlettered imply an inability to read as well as to write. I have this table definition as part of a invoice  \begin{tabularx}{\textwidth}[ht]{lXrr}%   It worked fine for years until I have a very short word in the X column for the first time. Now my table is very small in width and centered horizontally on the page.  In my expectation the X column should fill up all space until the width of the table reaches the width of the page except the margins.  I have read about workarounds specifying something like 1.2\textwidth, but I don't like that, because the table is a template included via \include, so it would affect all my invoices.  I also tried \linewidth, \hsize and \columnwidth, but everything results in the same layout.  Is there a way to make the only X column expand so that it uses all available space?    Complete included table definition (Rechnungstabelle.tex):  \newcommand{\Rechnungstabelle}[4]{% vielen Dank für Ihren Auftrag. \noindent \begin{tabularx}{\textwidth}[ht]{lXrr}% \toprule% \bf{Anzahl} &amp; \bf{Bezeichnung} &amp; \bf{Einzelpreis} &amp; \bf{Gesamtpreis} \\% \midrule% #1% \bottomrule% &amp; \bf{Rechnungsbetrag}  &amp; &amp; \bf{\EUR{#2}} \\% \ifthenelse{\equal{#3}{}}{}{&amp; Enthaltene MwSt. 19\% &amp; &amp; \EUR{#3} \\}% \ifthenelse{\equal{#4}{}}{}{&amp; * Enthaltene MwSt. 7\% &amp; &amp; \EUR{#4} \\}% \end{tabularx}% }   Changing the table header row to  \bf{Anzahl} &amp; \bf{Bezeichnung} \hspace{\textwidth} &amp; \bf{Einzelpreis} &amp; \bf{Gesamtpreis} \\%   is a workaround, but I don't think that would be good TeX style.

I am fairly new to Stack Overflow and just stumbled across Meta Stack Overflow.  I can't seem to figure out what the purpose of the "Meta" site is. Can someone please explain it to me? I've heard a lot about the Undying Lands but I don't fully understand how they're different from Middle-earth and why only certain people/races are allowed to go there.  Can someone explain? Can magnets rotate infinitely? Need polite phrases expressing disagreement with the information/conclusions of another person, especially an educator What pins on a nRF51822 do I connect to a STM32 programmer? In Russian we have idiom/saying "To shoot out of cannon into sparrows" (literal translation) which is used to convey an idea of applying too drastic measures to small problems. I believe there should be some native-English equivalents to this saying. Can you share if there are any? How to show or hide Keyboard Viewer with a keyboard shortcut? I would like to display and hide the Keyboard Viewer using a shortcut.   Is there a way to display the Keyboard Viewer via a keyboard shortcut? Is there a way to automatically display the Keyboard Viewer once I switch to a specific language? Indent entire section using only preamble I heavily use org-mode in Emacs to create TODO lists with timekeeping, which has a handy export to LaTeX feature. The problem is that in order to get my exported LaTeX document to look right, I want to indent entire sections, essentially treating sections like lists. It's very easy to create a template to copy and paste into every new file, but not feasible to edit the text directly as this would interfere with org-modes ease of use. Thus:  Is there a way to indent an entire section, using only the preamble?  MWE  \documentclass{article} \usepackage[explicit]{titlesec} \setcounter{secnumdepth}{0} \newcommand{\clock}{CLOCK: number number number \\}  \titleformat{\section}{\bfseries{}}{\roman{section}}{3pt}{#1} \titlespacing*{\section}{0pt}{0pt}{0pt} \titleformat{\subsection}{\bfseries{}}{\roman{subsection}}{3pt}{$\rightarrow$#1} \titlespacing*{\subsection}{2em}{0pt}{0pt} \begin{document}   \section{First section} \clock  \section{Second section} \clock \clock \clock  \subsection{First subsection} \clock \clock  \subsection{Second subsection} \clock  \subsection{Third subsection} \clock  \end{document}   I want the text with the red arrow to be indented to the same level as the section. While building things I want to see the overlays from other modes so I can make better decisions. Can I lock an overlay somehow?  For example: When building roads I want to see the natural resources overlay. When zoning I want to see the wind overlay My keyboard is typing by itself, could there be a ghost in it? The keyboard on my laptop seems to be typing by itself:   It sometimes types characters like 134, whether by itself or when I hit certain keys. Repeating characters may appear unexpectedly. The system volume may change by itself, or windows like the Print dialog or Web browser may appear.   This can happen without any input or as I type, and may occur more often when certain keys are pressed. Sometimes, the keyboard fails to respond altogether. This is happening regardless of the software involved.  Is there a ghost in my keyboard—is my keyboard broken?  A sample of text from the keyboard might look like this (normal QWERTY...ASDF...ZXC... sequence is expected):   QWERTYUIOPASDF)(G@*HKLZXCVBN QWERTYIOPASDFGL!#ZXCVB13 QWERTYUIOPASDFGHJKLZXCVB!#N qwertyu41iopasdf19g13h28j113k4113zxcvb4n qwerty4u1iopasdf0g7h1jklzxcvb13m qwert13uuuuuuuuuuuuuuuiopasdf87091134ghhhhhhhhhhhhhhhhhhhhhhh13jk13zxcvb14      This question comes up often and the answers are usually the same.

What is the correct way to use infinitive after the verb "help": with or without "to"? What is the correct way to use infinitive after the verb "help": with or without "to"?  For example:     Please, help me to understand this.   or:     Please, help me understand this. I want to kill a whole process tree.  What is the best way to do this using any common scripting languages? I am looking for a simple solution.
