https://tex.stackexchange.com/questions/695032 | 0 | I often have the problem when speaking about a LaTeX document that I say e.g. "please see 3.5" and that only then I realize that this could refer to a) a section, b) a equation and c) a figure and therefor then add e.g. "eh… I mean *section* 3.5". Is there some way to only have *one* namespace for chapters/sections, equations and figures?
There seems to be nothing on the internet about that yet (probably because it'd look awful), so any help is appreciated.

https://tex.stackexchange.com/questions/694946 | -1 | In this resume template: How can I move the output of the command `\cvdetail` to the left most side? Nothing seems to work for me.
Link: <https://www.overleaf.com/latex/templates/resume/rysrqppxyvdg>
| https://tex.stackexchange.com/users/299988 | CV template in overleaf | false | Just guessing, what "move to left" might or might not mean, I suspect you want to rewrite the `\newcommand`:
* now it's a table
* where the first entry is empty
* AND its width is set to 2.5cm via `p{2.5cm}`
```
\newcommand{\cvdetail}[1]{
\begin{tabular*}{1\textwidth}{p{2.5cm} p{14.5cm}}
& \larrow{bgcol} #1\\ [3pt]
\end{tabular*}
}
```
So adjust the width to less than 2.5 cm, OR remove the table at all:
```
\newcommand{\cvdetail}[1]{
% \begin{tabular*}{1\textwidth}{p{2.5cm} p{14.5cm}}
% &
\larrow{bgcol} #1\\ [3pt]

Can someone please help me to align this table in the center of the page?
| https://tex.stackexchange.com/users/218653 | Table is exceeding the right margin | false | The `tabular` environment in your code fits fine. What's missing is a `\centering` directive, so that the table and its caption are both centered.
Some further suggestions, in no particular order:
* Since almost all contents of the table are "math-y", I'd use an `array` environment instead of a `tabular` environment.
* The `palatino` package is obsolete, just as the `times` package is. I suggest you load the `newpxtext` package instead of the `palatino` package. I'd further load the `newpxmath` package, to provide a Palatino-clone math font package. (Palatino text and Computer Modern math do not harmonize well.)
* I can see no reason for **bold-facing** the contents of the table's header row.
* The preamble code contains several minor inefficencies. I've commented on some of them in the code below. Do check if you could remove some of the cruft that's present in your document's preamble.

\usepackage[T1]{fontenc}
\begin{document}
\noindent\scshape{Hello World}\\
\textsc{Hello World}
\end{document}
```
Explanation and question:
=========================
As you can see, I am working with a `memoir` document class and I've load a font `DejaVuSerifCondensed`, I am trying to obtain small caps for my header (which I did not place in the MWE as unnecessary). However I can't obtain the desire effect with the `\scshape` command nor with the `\textsc{}`.
I've seen other questions like
* [When using \textsc, LaTeX issues warning: Font shape `OT1/cmr/bx/sc' undefined](https://tex.stackexchange.com/questions/37618/a-problem-with-textsc)
* [Small Caps and Bold Face](https://tex.stackexchange.com/questions/27411/small-caps-and-bold-face)
* [Small Caps not Working](https://tex.stackexchange.com/questions/187398/small-caps-not-working).
But either they do not adapt to my problem (for what I can see) or they do not solve the problem (following the instructions there and "inserting" the piece of code in mine).
Question here is: is there a general method (piece of code or something) to obtain small caps from a custom font (even if that is one I upload with a ttf)?, if not, what would be the piece of code to select the *standard* small caps font?
| https://tex.stackexchange.com/users/42784 | Is there a general method for obtaining small caps with custom fonts? | false | This is the only post I could find with actual productive discussion of how to create fake small caps on stackexchange, so I thought I would chime in with an additional method I found [on the latex.org forum](https://latex.org/forum/viewtopic.php?t=18301). I'm retranscribing here in case the link dies in the future, and making minor alterations for readability.

The code apparently originally comes from the French programming-support forum *Le site du Zéro* which eventually became OpenClassrooms, which now mainly offer actual courses. Though not indexed by search engines, some of the [old forum content](https://openclassrooms.com/forum/) is available -- but I couldn't find the specific post this code came from.
