inheriting size characteristics
Dear fellow knights, Given predefined switches like \tf and \bf, one inherits the size characteristics of the one already declared. But for user-defined switches this does not work. The following minimal files (typescript and test) is a bit long, but it accurately illustrates the problem and uses the default fonts. My user-defined switch works, but does not inherit from, e.g., \tfc. But \bf does inherit. What am I missing?

Idris, I don't have time to really delve into the implementation details, but it looks like the difference is that ConTeXt isn't so responsive with user- defined alternatives with more than two characters. Compare the stripped down version with your own. Your \scsb has been changed to \SB, effectively. Note the tricks that can happen behind the scenes: \SBc isn't defined, but still \SB gets scaled at `c'. \SBb is defined as scaled to something different, and the switch picks up that fact. In short, there's a lot of subtle, tricky stuff going on behind the scenes that I don't understand fully: %D The in-file typescript requires a recent beta! \starttypescript[serif] [lm][default] \definefontsynonym [LM] [texnansi-lmr12] \definefontsynonym [LMBold] [texnansi-lmbx12] \definefontsynonym [LMSemiboldCaps] [texnansi-lmro12] \stoptypescript \starttypescript[serif] [lm] [size] \definebodyfont [12pt] [rm] [tf=LM sa 1, bf= LMBold sa 1, SB= LMSemiboldCaps sa 1, SBa=LMSemiboldCaps sa a, SBb=LMSemiboldCaps sa d, % !!! % SBc=LMSemiboldCaps sa c, % !!!

indeed the two chars is a limitation (i may be able to get around it but it will probably involve some magic, late nights, headaches, etc) Hans ----------------------------------------------------------------- Hans Hagen | PRAGMA ADE Ridderstraat 27 | 8061 GH Hasselt | The Netherlands tel: 038 477 53 69 | fax: 038 477 53 74 | www.pragma-ade.com | www.pragma-pod.nl -----------------------------------------------------------------
