Often referenced questions

I keep seeing the same bad coding styles being used in MWE or even recommended in answers or comments. There are also some FAQs (like the famous and repeatable asked how-to-place-my-figure-here question) which need to be linked to the appropriate existing question. Sometimes I have issues finding the related question quickly even if I already linked to it a couple of times before.

So I thought it would be good to have a collection of such often references questions sorted after topic in a meta post similar to our create Text building blocks.

Questions should be listed after topic. Every topic as CW answer to this post. Please use the following format:

## Topic Headline at Start of Answer Post

* [question title](http://tex.stackexchange.com/q/<question id>) [2 spaces] [linebreak]
[question title](http://tex.stackexchange.com/q/<question id>)


This way the question is provided as link (for quick access from this page) as well as markdown code suitable for comments (and as in-line link in a chat message). The URL can be received by using the link link below a question. There is also an stackapps app (modified by me) which produces this format. The include /<user id> should be removed to have the links in a neutral form. The two spaces and line break after the first line makes sure that the code starts at a new line.

Topic headers at the start of every answer post should be done using second order headlines, i.e. ## Topic. The first order headlines are a little to large IMHO.

• Great list: thanks Martin!

• @Jake: I was thinking to add a bullet-point list at the bottom myself, but it didn't looked good. I like the top list in this form much better.

• @MartinScharrer I'm not sure if the format with several categories in separate answers is working out. We have 26 questions in 12 answers, that's about two per category, and whenever I want to add a question, I'm having trouble finding the right category. One answer with broader categories might be a better solution and more flexible? Nov 16 '12 at 21:34
• @JosephWright Would it be useful to add tex.stackexchange.com/questions/255709/… here? If so, does it belong with Installing or Fonts? I hesitate to just add it because it may be only frequently referenced by me and I don't want to use this meta-post for self-advertising ....

• I'd suggest tex.stackexchange.com/questions/7453/… as the canonical question about %, as it doesn't contain a second question about braces. Jun 27 '12 at 16:05

Paragraph shaping

• there are many, many questions that ask why there isn't a space following some command; many could be combined, but most haven't. i've just added the [spacing] tag to several that didn't have it (apologies for kicking them to the active list; most did have the tag already). i think this concept is a good candidate for addition here, but can't decide among the pertinent questions. some candidates (only the numbers, or i'll run out of space here): 14526, 17730, 17872 (closed ==> 17730), 25820, 29211, 44878, 79760 (closed ==> 14526), probably more Oct 30 '12 at 21:16
• since you're the one who added this category, there are quite a few questions about removing vertical space, especially before chapter headings. among them (numbers only): 17299, 39988, 43087, 44751, 70156, 79232, 109722, possibly more. i didn't check for xrefs, but suspect that there are some.

Old font macros

I need the following text quite often, so I post it here:

Please note that the \it, \bf, etc. font macros are deprecated because
they do not use the new font selection scheme introduced with LaTeX2e.
Please use {\itshape ..}, {\bfseries ..} or \textit{..}, \textbf{..} instead.
See [Does it matter if I use \textit or \it, \bfseries or \bf, etc.](https://tex.stackexchange.com/q/516)
and [Will two-letter font style commands (\bf, \it, …) ever be resurrected in LaTeX?](https://tex.stackexchange.com/q/15361)

• @Troy Thanks. The question had been closed (as duplicate, but the dupe was deleted as well), and later deleted. But neither that question nor the duplicate had any answers, so I just removed the entry from the post. If you're wondering, it was about drawing this: texample.net/tikz/examples/multiplexer May 9 '17 at 10:33
