Useful notes for some of my answers:

CTAN lion drawing by Duane Bibby.

How do you accept an answer?](http://meta.tex.stackexchange.com/q/1852/3954)

minimal working example](http://www.minimalbeispiel.de/mini-en.html)

The demo option for graphicx simply replaces actual figures with black rectangles; do not use that option in your actual document.

comment pgf plot and foreach loop
+1. Or with \pgfplotsinvokeforach, one can say \begin{axis}[grid=major, xmin=-5, xmax=5, ymin=-30, ymax=30, xlabel=$t$, ylabel=$y$]; \pgfplotsinvokeforeach{-2.4,-1.8,...,2.4}{ \addplot [domain=-5:5, samples=100, color=cyan]{#1*x^2}; } \pgfplotsinvokeforeach{-2.1,-1.5,...,2.4}{ \addplot [domain=-5:5, samples=100, color=red,dashed]{#1*x^2}; } \end{axis}

comment Horizontal - Vertical connectors in a tree (in place of slanted lines)
@SašoŽivanović I would also be happy to beta-test the new version (by the way, good to hear about a new version!). Please ping me here (if that's OK with cfr) for any message.

comment Descriptive text for figure depending on location
@Bernard Are you sure? As far as I recall, cleveref only records the kind of object, but not its location, so \Cref{fig:figurename} will only give Figure #. On the other hand, as David suggested, varioref adds a location-associated string.

comment Pyramid Commutative Diagram for Cones
@Exterior Change \coordinate (appex2) at (-2.5,4); to \coordinate (appex2) at (-2.5,4.3); (instead of 4.3 use the desired value.)

Yes, of course I noticed. I just wanted to make it explicit and to acknowledge your involvement in the forest crusade!

Good to see that you also like forest :)

@egreg Yes, I should've thought about it.

comment \beamergotobutton size
@PatrickT Indeed; the size of the button is not easily changed using user hooks. You can see the definition of the button (which, by the way, is built using PGF) in, for example, beamerinnerthemedefault.sty. You'll notice that the dimensions of the button are hard-coded, so it's simpler to use a user-based modification as the one in my answer. Of course, you can avoid using TikZ and you can use PGF directly (as the class does), if you don't want to load TikZ.

@user3624246 Then what is that you want to number?

Add \numberwithin{theorem}{subsection}.

comment biber stopped working?
Of course that line is necessary, but have you actually executed biber? Otherwise, no bibliography will be generated.

Did you actually run biber (or BiBTeX)?

comment Technical Drawing Using LaTeX
@RicardoVelozJr You're welcome. For the powerful TikZ, you have the PGF/TikZ manual (texdoc pgf in a terminal, or in CTAN: mirrors.ctan.org/graphics/pgf/base/doc/pgfmanual.pdf).

comment yticklabels Problems
@leoleoleo I've provided an answer below. Is something like that what you want? By the way, when I asked you to add a simple test file diffecorrenti.txt to your question, I didn0t mean the actual file, but a simple dummy file like the one in my answer.

comment Removing extra space in alignat
Why alignat with so many alignment points? It's perfectly OK to do \documentclass{article} \usepackage{amsmath} \begin{document} \begin{align*} \Phi \Bigl(\sum\limits_{m\in M}r_m\delta _m + \sum\limits_{m\in M}r_m'\delta _m\Bigr) &= \Phi \Bigl( \sum\limits_{m\in M}r_m\delta _m + r_m'\delta _ m\Bigr)\\ &= \sum\limits_{m\in M}(r_m+r_m')\phi (m)\\ &= \sum\limits_{m\in M}r_m\phi (m) + \sum\limits_{m\in M}r_m'\phi (m)\\ &=\Phi \Bigl( \sum\limits_{m\in M}r_m\delta _m\Bigr) + \Phi \Bigl( \sum\limits_{m\in M}r_m'\delta _m\Bigr) \end{align*} \end{document} I also reduced the parenthesis size.

comment yticklabels Problems
Please add to your question a simple test file diffecorrenti.txt so your example becomes quickly compilable for everyone.
