Ahoi, Following a previous discussion, I've been advised to "try to avoid \switchtobodyfont and use \definedfont or \definefont instead". (1) What's the difference between \definefont and \definedfont ? (2) In the underneath example... (2a) how to implement \define(d)font for font switching ? (2b) how to define \myFontHook ? Thanks, Alan \usemodule[t-lettrine] \usetypescriptfile[tps_arial] \usetypescript[arial] \definetypeface[myFont][arial] \usetypescriptfile[tps_timesnewroman] \usetypescript[timesnewroman] \definetypeface[myOtherFont][timesnewroman] \def\myFontSize{12pt} \def\myOtherFontSize{20pt} \setupbodyfont[myFont,\myFontSize] \setuphead[chapter][style={\switchtobodyfont[myOtherFont,\myOtherFontSize]}] \starttext \chapter{Chapter One} %\lettrine[FontHook={\myFontHook}]{T}{hus}, I came to the conclusion that the designer of a new \lettrine{T}{hus}, I came to the conclusion that the designer of a new system must not only be the implementer and first large-- scale user; the designer should also write the first user manual. \stoptext
