TeX provides calligraphic alphabets, which can be accessed using <{{cmd>|cal</cmd> }} however, there are no script alphabets in Computer Modern or Latin Modern. Raph Smith's Formal Font [http://www.ctan.org/tex-archive/fonts/rsfs/] provides script alphabets that blend well with Computer Modern and Latin Modern. They can be used inside ConTeXt as follows

With these defintions one can use <{{cmd>|scr</cmd> }} just like <{{cmd>|cal</cmd>}}. This method has the advantage that it uses different fonts (rsfs10, rsfs7, rsfs5) in body script and scriptscipt.
