For the article Barbara mentioned I used for example a style option called concrete which defined a version euler to set math formulas in the same way as it was done in Dons book Concrete Math. > - LaTeX needs a font selection scheme that allows a designer > (user) to switch fonts INSIDE formulae The work one the amstex project also contains a style option amsbsy which defines one single command \boldsymbol which could be used to type a single letter or symbol in bold. Internally this is defined via \mathchoice and a switch to the bold version (i.e. \boldmath). This implementation shows that it is possible to overcome the limit of 16 math families if necessary. A similar command could be defined to switch for a single symbol to another, for example the euler version, if desired. If Barbara likes she is welcome to submit our article via this list but you will not be able to process it since you nead the new font selection. But I would like to concentrate on other points at the moment. I have a bit a problem that many different topics are raised. So I will go back to the generic commands (still waiting for comments). Yesterday evening I implemented a draft version as outlined in my last message. It is now working (with some unfinished parts) and I was able to set up a IBM-manual style in less than 10 minutes (i.e. headings in the left, sans serif bold headings, thick rules above the section title, thin rules across the whole page above subsection titles and so on. (I tried this once in LATeX 2.09 ...) As I said yesterday some more utilities are needed. For example a test macro to check if an argument fits into a given space without line breaks, would be nice. But probably there are some more. The current LaTeX has a nice mechanism to ensure that a heading is always (well, nearly always) followed by at least two lines. While this is nice but I wonder if we don't need a better method to to do this work. The question is do we have to give the designer the possibility to specify a number of lines or a space or what which has to follow a heading? Comments please !!! With TeX30 this should be no problem to implement this. Greetins Frank
