Linux (Debian) user since long time ago, some of my actual fields of interest are currently improve my limited skills with LaTeX and R (at the same time thanks to Sweave). My apologies if you find unclear anything of what I write. English is not my native language and I've never been in any type of regular English courses.

Precooked comments: Text building blocks

Welcome to TeX.sx! Please add a minimal working example (MWE) that illustrates your problem. It will be much easier for us to reproduce your situation and find out what the issue is when we see compilable code, starting with \documentclass{...} and ending with \end{document}.

A tip: If you indent lines by 4 spaces or enclose words in backticks ```, they'll be marked as code, as can be seen in my edit. You can also highlight the code and click the "code" button (with "{}" on it).

BTW, it is safer user \linewidth that \textwidth. See what happen with this figure if you add twocolumn options to the document class, or if the figure is part of of a item in a list, for example. See tex.stackexchange.com/a/142709/11604

Your figure go to the top of the page because you are using the t op option in figure. Change [!tpb] by just [bp] or [hbp]. BTW, \centering is superfluous here. BTW, may be you are searching for one figure with three subfigures? In this case use the subfig or subcaption packages instead of minipages.

comment Recommended workflow for fixing several nasty frames in beamer?
Too obvious, but if you are working in the 4th of 200 frames, the easiest is just place a temporal \end{document} after the 4th frame (equally obvious, this is of little help when you are working in the 195th frame).

@delimeterfont You can adjust the height as you whish with \raisebox. I edited the answer to insert an example.

comment Why does LaTeX macro spells \LaTeX{} (which requires Shift) and not \latex{}?
Because typing simplicity is not always desirable. Replace "are" by "r", "you" by "u", etc and you save a lot of keystrokes, but your text is hardly readable. Lowercase names and surnames is unpleasant and may be confusing ("agate brown": A girl or a dark stone?) and it is well-know that this is also true for "LaTeX" vs. "latex". In the old times without syntax highlighting, that was is some extent true for \LaTeX. A highlighted \LaTeX is more clear that \latex? Not sure, but tradition still matters.

comment How to check if a macro from <some package> is used in a document?
@egreg, Certainly, I should have advised that there parasitic clasess and parasitic packages. In your example one could say that is a "nested definition" trough \RequirePackage{amsmath}[2000/07/18] that load \newcommand{\boxed}[1]{\fbox{\m@th$\displaystyle#1$}}, but from the practical point of view (e.g., prevent not working macros due to removed package) this is mainly irrelevant.
