I know that we can use CtrlLeft Click to add a file to the selection in windows explorer. It is also possible to use ShiftArrow to extend the selction to adjacent files.  How can I select files that are not adjacent though - without using the mouse?  I noticed that I can use CtrlArrow to move some kind of cursor onto a file without actually selecting it, but then how can I select the file I want selected once that cursor is on it?  Bonus Points if you also know how to jump to a filename and add this to the selection, but that would be a different question
If I've got a file (or files) selected in Windows Explorer, the only way I've found to "unselect" them is click with the mouse on some empty space.  I thought Esc would do this, but it doesn't. Also changing focus with Tab or Shift + Tab doesn't work; the file(s) are still selected even if focus goes to the address bar for instance.  Does anyone know of a keyboard shortcut to do this?
What part of speech is "back" in "put the book back on the table"? Put the book back on the table.   I'm having trouble. I think it is a preposition. How to strike through obliquely, e.g. to indicate cancellation? How can I strike through an expression (e.g. "2x") obliquely, e.g. from bottom left to top right, so as to indicate cancellation? With the \sout command from the ulem package, I can only strike horizontally. How does one decide whether to use who or that? In the title example:   The correct pronoun is who. The correct pronoun is that. Either is correct. They're interchangeable. It depends on the context. How can I change the Windows 7 Logon Screen wallpaper? Let $\Gamma$ be a circle that passes through the origin. Show that we can find real numbers $s$ and $t$ such that $\Gamma$ is the graph of $r = 2s \cos (\theta + t).$  I know this has to be converted to a cartesian equation, but how do I do this, and what do I do after?  Thanks Why are low-rep users rate-limited when posting questions? I just encountered the following error:  Oops!

Reproducible LaTeX builds - compile to a file which always hashes to the same value List has no rows for assignment to SObject What is the number of automorphisms (including identity) for permutation group $S_3$ on 3 letters? What is the number of automorphisms (including identity) for permutation group $S_3$ on 3 letters?  I believe the answer for this is 6. As we can write the group elements as below   (a)(b)(C) (ab)(c) (ac)(b) (bc)(a) (abc) (bac)   Can we generalize that for any $S_n$ onto $n$ the number of automorphisms will be $n!$ Also I cannot find this anywhere in my text, can we have a permutation $S_n$ onto $m$ where $n\neq m$? (for eg: is it possible to have a permutation group say $S_5$ on say 2 elements?) Let $K=F[x]/(p(x))$, where $F$ is a field, $p(x)\in F[x]$ is an irreducible polynomial.  What are all the maximal ideals in $K[y]$?  Attempt: I have an attempt, but not entirely sure it is correct.  Since $(p(x))$ is a maximal ideal in $F[x]$, this means $K$ is actually a field.  Thus $K[y]$ is a PID.  So maximal ideals in $K[y]$ are $(g(y))$ for irreducible polynomials $g(y)\in K[y]$? Huge close votes review queue on Stack Overflow Detecting unused packages in LaTeX document I have quite a bad habit of copy-and-pasting my packages from one LaTeX document to another. Is there any way we can detect unused packages (i.e. \usepackage commands) so that they can be removed from the LaTeX document? In terminal emulation applications, pressing CTRL + Left / Right arrows jumps from one word to the previous or next one. Is it possible to have the same functionality in a Linux console, whether it is in text or in framebuffer modes?  In my configuration, the CTRL + arrow keys are transformed into escaped character sequences and not interpreted. How to split numbers into columns with negative and positive values, without empty cells? Do Stack Exchange sites allow editing of comments and posts from other users? I am trying to think of what the name of the word/phrase is for when: An important task (not a difficult one, but a mission critical one) is at hand and instead of one person being assigned to it, a group takes on the responsibility to mitigate any consequences happening to one person in case something goes wrong and also to prevent a mistake or malicious intent occurring from one persons doing. (NOT because the task is big and needs to be divided in a group.) E.g.   Two different people needing to turn a key each in a device simultaneously to launch a missile.  Group of people tallying up votes for an election in case one of them were bridged to rig the outcome. I am writing a cover letter and CV using moderncv. Everything works fine so far, but the text in the cover letter is not justified. I think it is good that it is not hyphenated, but it would look much nicer if the text was justified.  Here is a minimal example:  \documentclass{moderncv} \moderncvstyle{classic}  \usepackage{lipsum} % just for dummy text  \firstname{John} \familyname{Doe}  \begin{document} \recipient{Prof.\ Dr.\ Foo Bar}{} \opening{Dear Professor Dr.\ Bar,} \closing{Yours sincerely,} \enclosure[Attached]{curriculum vit\ae}  \makelettertitle \lipsum[1] \makeletterclosing  \clearpage  \makecvtitle  \section{Education} \cventry{2009--present}{PhD Student}{here}{and}{there}{} \end{document} I've shown the existence of unique square roots of all positive rational numbers, so now I want to prove that the square root is monotone:   $0&lt;a&lt;b$ if and only if $\sqrt{a} &lt; \sqrt{b}$ How to interpret these acf and pacf plots I was just chatting on the Ask Different chat - and the reputation numbers for me and the others chatting don't seem to match any other reputation count I can see on the sites here.  Is there some calculation being made? These numbers are the highest of any other combined reputation I have seen. For me - I'm listed over 10k - but no other aggregate reputation counter I can see is above 8k.  Perhaps I'm unaware how reputation is calculated, but the people there suggested a bug report in case this isn't intended.
