| Sometimes I find a solution to a TeXnical problem, and I think everybody should know about it. Some of these things are totally obvious, but (as far as I know) non-standard.
| | Now I'm like, well duh! Truly thanfkul for your help. |

| ==BibTeX without a separate .bib file==

| |
| | |
| $Bib\TeX$ has the nice feature that it makes your bibliography
| |
| nicely; the entries are all formatted the same way, and it is
| |
| easy to change that format. However, it is annoying that you
| |
| have to have a separate <code>.bib</code> file to contain all your
| |
| bibliography entries. Fortunately, it is not too hard to build
| |
| the <code>.bib</code> file into the <code>.tex</code> file. To illustrate,
| |
| the source of [Ant06] is (sorta) included below.
| |
| Note that you have to run $\LaTeX$, $Bib\TeX$, $\LaTeX$, $\LaTeX$, as
| |
| usual when you use $Bib\TeX$.

| ==Placing labels on arrows in XY-pic==
| |
| (I learned this trick from [http://www.math.columbia.edu/~lauda/ Aaron Lauda]; I haven't seen it documented anywhere)
| |
| \xymatrix{asdfasdf \ar[r]^{f} & a }
| |
| produces the label "f" in a stupid place, half-way between the centers of the two entries, instead of where you'd like it to be, half-way along the arrow. One way to handle this is to do something like <code>\ar[r]^(.7){f}</code> but that is fairly unsatisfying because you have to calibrate the (.7) by eye. There is another way, which is to use
| |
| \ar[r]^-{f}
| |
| which will automatically place the label "f" half-way along the arrow. If you want the label .7 of the way ''along the arrow'', you can do <code>\ar[r]^-(.7){f}</code>.
