[NTG-context] fullpage and XeTeX typescript

hi, 1. what's the equivalent of the \usepackage{fullpage} for ConTeXt? 2. it would be convenient if LuaTeX supported typescripts like XeTeX does instead of having to define font synonyms, e.g., \definetypeface[mainface][rm][Xserif][Warnock Pro] \definetypeface[mainface][ss][Xsans][Cronos Pro] \definetypeface[mainface][tt][Xmono][Inconsolata][default]%[rscale=0.9] % use only for Monaco %\definetypeface[mainface][mm][Xmath][palatino] \definetypeface[mainface][mm][math][palatino][default]%[encoding=texnansi] \setupbodyfont[mainface, 13pt]
