comment How to emphasize within a listing two successive identifiers separated by a space?
Furthermore, it seems unlikely that a small amount of TeX hacking will make it convenient to use space characters valid in keywords, because they are most often used to determine the boundaries of keywords: any keyword which was bracketed by space characters would not be recognised.

I would highly recommend \usepackage{bbm} and \newcommand\idop{\bbm 1}.

Why don't you playing around with it and find out, and try putting other things between the & characters? I could try to describe it in detail, but I'm not going to get much clearer than what I've already said, unfortunately.

@alexjlockwood: typically, it means "advance to the next column". In eqnarray (don't use it!) equations are blocked into groups of three columns: right-aligned, center-aligned, and left-aligned, after which you jump rightwards some distance to start a new equation further to the right. In align, equations are blocked into groups of two columns: right-aligned, and left-aligned. You'll also encounter & any time you use a table, or a matrix, or similar sorts of environments.

@alexjlockwood: in a word — never. What was the second question?

comment How to correctly format (and align) a LaTeX proof?
Hm. I didn't know that, perhaps as a result of not using lefteqn. I adopted this method (those rare times when I've used it) as it is a way of getting remarks flush with equation numbers.

comment How to make an arrow bigger and change its color in TikZ?
What do you mean by "bigger... without impacting the line"? Do you mean just to increase the size of the arrow-head?

comment Draw an arc between 2 nodes and label it in TikZ
Thanks. Generally, you should post a complete working document in such cases, to avoid such confusion. (Especially where TiKZ is involved, which has more accessories than the proverbial Malibu Stacy doll.)

Your code does not compile for me. What TiKZ libraries are you using?

comment Obstacles to simulating an amsmath matrix by a TiKZ matrix of math nodes
With experimentation, I found some minor improvements: row-spacing should be set to {\mtxrowsep,between borders} in order for the spacing to be correct at different typeface sizes; and the value of \mtxrowsep should be changed to \arraystretch\baselineskip as the first step in the wrapper environments to get the correct row-spacing. I found that inner ysep=0.7ex and inner xsep=0 to be better than a symmetric inner sep. Finally, depending on the font size, yshift values ranging from 0 to 1ex may be needed. This gives essentially robust results for different matrix dimensions.
