From LaTeX to ConTeXt
General hints: LaTeX in proper ConTeXt by Berend de Boer
Special things that you've been used to do with LaTeX, but that are not so obvious to do with ConTeXt.
- Bold small caps
- Bold typewriter
- Description
- Flush bottom
- Verbatim with line breaks
- Typearea
- PDF-strings
- Commands with optional arguments
- ISO-8859-15
Also, many of the macros on the LaTeX Math in ConTeXt page are equally useful in ConTeXt formulas.
