[NTG-context] confused on font size

[Paul Tremblay]

The main manual on ConTeXt give a number of different ways to change
font sizes (if I understand it correctly):


1. {\switchtobodyfont[18pt] text}

2. {\tfx font size ??}

3. {\xii some font}

What are the advantages of each? I would think that option (1) would
be the simplest and clearest to use.

Thanks 

Paul
