ConTeXt uses the Latin Modern fonts by default; these fonts looksimilar to the original Computer Modern fonts, but have a much largercharacter repertoire. As it happens, in the Latin Modern (and ComputerModern) fonts, the slanted font does not stand out from theupright font enough for some tastes; so, many people prefer to use theitalic font for emphasis. To do that use <texcode>\definebodyfontenvironment[default][em=italic]</texcodecontext>
