The sentence     LaTeX is fun   is produced by  \LaTeX\ is fun   Why does Latex tend to swallow the space between the words 'Latex' and 'is' unless the space is escaped by a backslash?

I have a sentence that contains a number of long dataset names. I would like to allow LaTeX to break these names at certain positions that I would like to specify somehow just like I can use \- to allow a word break with hyphenation. But: I would like LaTeX not to insert a dash (which could be mistaken as belonging to the dataset name). How can I do this?   (Something similar is realized in the url package so I guess I could just read that code :) I would not like to use the url package here to be able to make a syntactical (and typographic) difference between urls and datset names.)

I cannot remember how to create an invisible character in LaTeX, i.e. I want to put a space that has the width of a particular character, say `M'. I know there is a command for this, and this is a really dumb question, but my Google-fu has failed me.

When using some other editors, when you type two spaces with your space bar, two spaces are effectively displayed. This is not the case in LaTeX (btw, that's not the case on these websites ;) ).  My question is barely simple I guess, but I didn't found some information about it on Google.  How to display two consecutive spaces in LaTeX (I mean two spaces horizontally, with the space bar).

could anyone please tell me how I can write "ℰ" in latex in both text and math enviroment? I have already tried $\mathscr{E}$ and $\mathcal{E}$, but none of those are satisfying.   What I want to have is     but not any of these

I receive the following errors:  ! Package minted Error: You must invoke LaTeX with the -shell-escape flag. !

How can I tell LaTeX to automatically split up the german word  Kontrast/Rausch-Verhältnis    into   Kontrast/Rausch-|Ver|hält|nis   LaTeX complains that "/" is not a letter.

When I delete a "word" in Bash, it will stop at certain characters like _ and /. For example, if I type  /foo/bar   and activate backward-kill-word (typically mapped to Alt-Backspace and/or Ctrl-w), the remaining text is  /foo/   . This does not correspond to $COMP_WORDBREAKS or . How can I detect (preferably in a running system, rather than the defaults in the code, since they presumably can be overridden) which characters are used to determine word breaks?

On any SE post one can use the backtick symbol ("`") in order to mark some text as being a piece of code, or computer output. For example: void main().  Is there a way to make use of "`" the same way in a LaTeX document?

In math mode, LaTeX inserts a small space after a comma. This looks nice in $a,b,c$, for example. But I don't like the way it looks when using a comma as a thousands separator, e.g., $x = 100,000$. (There is no space after the comma when writing 100,000 outside of math mode.) Is there an easy way to avoid this? Some symbol I should be using instead of comma?

I am using a Mac with TeX Live and Mendeley for automatically generating .bib files, some of which have spaces in the file names. I would like to know how to reference such files from LaTeX as using "" or \ doesn't seem to work.

I can't find where I can remove any kind of hyphenation and just have LaTeX just do a line break.  edit: Honestly speaking I just don't like to read hyphenation anywhere and that's the only reason why I wanted to remove it. It is a matter of style, probably unexpected in LaTeX.  The document has only a summary in a different language and I used the language packages to hyphenate properly.

Is it possible to modify LaTeX so that good old $$...$$ behaves like \[...\] (and by this I mean that it should be synonymous to it).  If yes: Dear LaTeX3 developer, please integrate this into LaTeX3! (Not that I really believe you will actually do this.)  MWE (even if I don't really see its use in this case):  \documentclass{article}  \begin{document}  I've forgotten we're not in the plain \TeX\ world anymore: $$ x = 3\alpha^2 + \beta   = \int f\, d\mu. $$  \end{document}

I just submitted a question () with an exclamation (!) at the end of the title (with one space between the word and the exclamation) but it turned in to question mark (?).   I removed the space between the word and the exclamation, then it shows normal.   Is this an intended feature?

By default, (La)TeX adds extra space between sentences. The exact rules are in the TeXbook, a summary by TH. can be found . What follows is is my "executive summary":   After any period (or quotation/exclamation mark) that doesn't follow a capital letter, TeX adds a font's "extra space" to the "normal (interword) space". For Computer Modern 10pt, the normal space is 3.33pt and the extra space 1.11pt, resulting in an intersentence space of 4.44pt (+33% compared to the nomal space, assuming no stretch and shrink). A sentence end after a capital letter is indicated by the \@ command: Ann is learning the ABC\@. To denote that a period after a lowercase letter doesn't end a sentence, one may use \@ as well as an explicit space: Prof.\@ Higgins or Prof.\ Higgins.   Intersentence spacing may be brought in line with normal spacing by issuing the \frenchspacing command. (This is the standard setting for certain languages, e.g. the  (n)german option of the babel package.) With \frenchspacing enabled, there's no need to use the \@ command. One may revert to (La)TeX's default behavour by issuing \nonfrenchspacing.  So, there's the choice between extra intersentence spacing and uniform spacing. What is missing in my opinion is a third option I'll call "tightened frenchspacing": normal (interword) spacing between sentences and decreased spacing after non-sentence ending periods. To be somewhat more precise (while still ignoring stretch and shrink), I envision the following:   Adhering to a font's ratio between "normal space" and "normal space plus extra space" (3:4 for Computer Modern), the intersentence space is set to the normal space. The space after non-sentence ending periods equals the normal space multiplied by the above ratio (resulting in a space of 2.5pt for Computer Modern). As with \nonfrenchspacing in effect, the \@ command is used to denote cases of special punctuation.   How should such a "tightened frenchspacing" option be implemented?  EDIT: Thanks to Mico for providing what may well be a stepping stone to a solution. Here's another attempt at clarification:   Simply reducing the spacing after any period is not what I had in mind. There should be a (tangible) difference between end-of sentence spaces and spaces after non-sentence-ending periods (only that the latter should be reduced instead the former augmented). If adhering to a font's normal space/extra space ratio is not possible, a solution that adds a fixed (reduced) space (say, a thin space) after non-sentence-ending periods will be accepted. For compatibility reasons, I'd prefer a solution that works with the traditional use of \@ (i.e allows "tightened frenchspacing" for existing documents without the need to change the document body). Should it turn out that a different set of "special punctuation" macros is needed, I'll accept this as a solution.

On some pages of my document LaTeX introduces a lot of spacing between my headline/paragraphs (around 5 times more than usual).  What is the reason for this and how can I avoid it? It seems it is trying to fill the page until the next chapter starts.

I realize that ! has special significance on the commandline in the context of the commandline history, but aside from that, in a runing script the exclamation mark can sometimes cause a parsing error. I think it has something to do with an event, but I have no idea what an event is or what it does.  Even so, the same command can behave differently in different situations. The last example, below, causes an error; but why, when the same code worked outside of the command substitution? .. using GNU bash   4.1.5    # This works, with or without a space between ! and p   { echo -e "foo\nbar" | sed -nre '/foo/! p'     echo -e "foo\nbar" | sed -nre '/foo/!p'; } # bar # bar  # This works, works when there is a space between ! and p   var="$(echo -e "foo\nbar" | sed -nre '/foo/! p')"; echo "$var" # bar  # This causes an ERROR, with NO space between ! and p   var="$(echo -e "foo\nbar" | sed -nre '/foo/!p')"; echo "$var" # bash: !p': event not found
