Some LaTeX niceties from George Grätzer’s More Math into LaTeX, unless cited otherwise. To be able to jump to the corresponding part of the LaTeX file by double clicking on the typeset output in the DVI file, make sure linking to source is active in your DVI viewer; in Yap make sure that the “Inverse DVI Search”option points to your LaTeX editor and, to see the “hot points,” that “Show Source Links” is checked in the “User Interface” option tab.
Note: The .pdf in the file latex_niceties-tex.pdf is a dummy extension. (WordPress does not yet allow uploading TeX source files.) This file must be renamed to latex_niceties.tex, from which the DVI output may be compiled.
