• For the redefining the header, you can use
  • \markboth – two parameters (left and right page) or \markright with just one parameter
    • \markboth{\uppercase{Summary}}{\uppercase{Summary}}
    • You should note that a left-hand heading is generated by the last \markboth command before the end of the page, while a right-hand heading is generated by the first \markboth or \markright that comes on the page if there is one, otherwise by the last one before the page. (source)
  • \chaptermark, \sectionmark, … with fancyhdr package
  • see http://en.wikibooks.org/wiki/LaTeX/Page_Layout for more details

• Useful page (and a figure) for lists:
  • http://latex.computersci.org/Reference/ListEnvironments

• foreach in TeX (thanks to TMA):
  • If you want to \dothis{} with each word in \foreach{Peter, Paul, John, Ringo}, you can do this as follows:
    • \def\foreach#1{\first#1,,}
    • \def\first#1,{\if,#1,\else\dothis{#1}\expandafter\first\fi}
  • and then write something here:
    • \def\dothis#1{ … whatever #1 … }

• Aligning an element in the line according to whether it fits in the rest of the line (TeX)
  • always right-aligned (from Petr Olšák's TeXbook naruby):

       \def\alignelemright #1\par{\unskip
          \nobreak\hfill\penalty71\hskip2em\hbox{}\nobreak\hfill
          \hbox{#1}\par}

• always left-aligned:

        \def\alignelemleft #1\par{\unskip
          \hbox{} \hskip 0pt plus 1fil \penalty0
          \hbox{#1}\hskip 0pt plus 1fill\hbox{}\par}

• align to the right, if it fits, or to the left in the new line:

       \def\alignelemrightorleft #1\par{\unskip
          \nobreak\hfill\penalty71\hskip2em
          \hbox{#1}\par}
