having just looked at the umpteenth question about \left
and \right
in a multi-line environment, i checked the
"often referenced questions" list
to see if there was a suitable link. no, that's missing. in fact, there are
only three questions listed in the "math environments" section.
so i searched for suitable candidates in the archive. there are a lot of helpful questions and answers (one such was suggested in a comment to the new question), but all of them are quite specific to particular circumstances. there's no single "great question".
i'm willing to pose such a question and write a comprehensive answer, but in order to make sure both the question and answer qualify as "great", i'd like some help.
what's the best way to tackle this? chat in a dedicated chatroom?
my experience with chat is that the size of the window is not conducive to detailed exposition, which means that an answer can't readily be compiled as a unit, only piecemeal. (i'd really want to draft such an answer off-line anyhow, in order to make use of an editor i'm used to, that doesn't encourage me to make mistakes.)
if someone is willing to join in this endeavour, i'll add to this question the list of questions i've already identified as containing potentially useful information.
while we're at it, are there any other good candidates for "often asked questions" about math environments?
addendum: i've been busy with "real work", and haven't drafted anything useful yet. but some good candidates have been proposed:
how do i align my (displayed) equations?
why can't i define a shorthand command for
align
?my equation requires multiple lines, with matching delimiters on different lines. how can i avoid the errors that i get with
\left
and\right
?how do i put a brace (bracket/parenthesis) around just part of a matrix?
what are good practices when applying underbraces and/or overbraces to an equation?
what command should i use for bits of text in math environments?
i'll post a separate question for each draft as i put it together -- or if someone else wants to make a start, please feel free. (should the drafts be community wiki?) in the meantime, please keep on making good suggestions.

/textual in subscripts. One could go days browsing the linked section of Which command should I use for textual subscripts in math mode?. The Top 5 voted question of the amsmath tag also make a good start (the first two relating to\mathrm
stuff). – Qrrbrbirlbel Sep 4 '13 at 20:58
