Here are some more instances in support of boojums (using pdfTeX , not XeTeX). A. For tagged PDF you may need to tag individual characters with attributes for accessibility and Copy/Paste, such as to get the PDF page-contents stream looking like: /Span <</Alt(...)/ActualText<FFEF....> >> BDC ... normal TeX-placed material ... EMC \pdfliteral page {.... } can provide the extra PDF coding lines, but this is 2 extra boojums for each actual character in the math list. B. I'm currently writing a paper describing a method to attach tooltips to mathematical symbols and expressions. After setting the chunks in boxes for measuring, this ultimately puts \pdfannot .... into the math-stream. To not affect spacing, this would need to be a boojum surely. I can supply instances where spacing has changed, by an extra thin space. Sometimes placing extra {...} avoids this extra space, other cases require a \! to fix. > > Zdeněk Wagner > http://hroch486.icpf.cas.cz/wagner/ > http://icebearsoft.euweb.cz > > > > David Is there a good tool or TeXnique that lets one see the contents of a math-stream, after all macros are processed, and during the internal page-construction stage? I'd like something a bit better than just examining box contents after using \tracingall . Cheers, Ross
