1d	revised	Checking if a string contains # with its original catcode markup-fix (space/␣)
1d	comment	Add annotations at right margin of plot The `execute at end plot visualization` code may not get executed twice, but the `add node at x` style gets with the `+` and without the mentioned options. To test it, add `\newcounter{test}` to the preamble and `/utils/exec=\stepcounter{test}\errmessage{\arabic{test}}` to the `add node at x` style. If you use the style twice (`[add node at x={3}{B4LYP},add node at x={4}{B3LYP}]`), you will get something similar to what @Jellby reported.
1d	comment	Add annotations at right margin of plot Without the options `cycle list name=linestyles*` and `clip mode=individual` the `execute at end plot visualization` gets executes twice.
1d	comment	*Modifying `` and `o` style tikz arrows so that they are centered at the end of line** A similar problem arises with the `\|` and the `[`/`]` arrows (well, actually, all arrows are defined this way): TikZ arrow tip is displaced
1d	comment	Add annotations at right margin of plot Related: Align pinned nodes in PGFplots
1d	answered	How can I \Aboxed a Matrix?
2d	comment	How can I \Aboxed a Matrix? Enclose the `pmatrix` in the `\Aboxed` version in a pair of braces `{ }`. The `\Aboxed` macro works by scanning its argument for `&`, the `{ }` hide those from it.
2d	comment	How to surround portions of a tree with boxes How do you create your trees? Can you show us your code? For TikZ-based solution the `fit` library will help.
2d	revised	trees wiki excerpt edited body
2d	comment	How do I embed an external image within tikzpicture? `\pgftext` is not a TikZ command. The `\node` thing from @Jubobs should work. `\pgftext[at={\pgfpoint{0pt}{0pt}}]{…}` and `\pgftext[x=100pt, y=0pt]{…}` are possible `\pgftext` solutions. (The `at …` stuff you wrote is just ignored by TikZ as usual.)
May 19	comment	Broken tikz chains Well, you don’t have a definition for the `terminal` nor the `nonterminal` style. The example (or another one) in the PGf manual, p. 61, defines them.
May 19	comment	homemade glyph in lualatex The kerning is wrong: `\normalk x = \kf x`. Maybe: `\ooalign{\hss\kern.05em\lower.7ex\hbox{\tiny f}\hss\cr k}` or `\rlap{\kern.18em\raise.7ex\hbox{\tiny f}}k`
May 18	comment	How to draw bent arrows going to a new line in long formulas (ex. chain complexes) @kan I have included a (hopefully) improved version of your answer. It uses text width instead of minimum size (which would have also changed the height). Is this the improvement you were talking about in your comment? Of course, OP’s way of using an empty column (containing only `{}` so that a node is created) is another possibility (I’d suggest to use `&[+0pt]`), sadly one has to keep track of all the columns.

May 18	comment	Which package should I use for doing a connecting homomorphism diagram like this in latex Ah, that was supposed to be xy-pic (the `\xymatrix` macro is what you are looking for). There are a few tikz-cd questions here that are very similar to your image (especially the long arrow): How to draw bent arrows going to a new line in long formulas (ex. chain complexes), How do you draw the "snake" arrow for the connecting homomorphism in the snake lemma? and Tikz-cd and snake lemma: "loseness" and centered figures.

May 18	comment	how to make this circles? @giannis That doesn’t look right. The `x radius` and `y radius` option do not have anything to do with the `node` and you’re missing at least the `{}` of the node. I wouldn’t include the node in the `saveuse path` either because it would be repeated for the `\draw` part. Let me update the answer with some ideas.
May 18	comment	how to make this circles? @giannis What do you mean? The big circle’s coordinate are accessible with `(<angle>:2.5cm and 1.75cm)`. You can place anything you want on it.
