I still have some questions.  It took me a long time to understand that

would use the fontfeature "hebrew" that I had defined together with
the font file SILEOTSR.ttf and assign this pairing to the nickname
"myhebrew".  Rik's example also has "sa 1" which I do not understand.

Michael,

Wolfgang already answered most of your questions, at least by the
expedient means of teaching a man to fish. However, not all of the
questions are answered in the font manuals, and in particular your
question about the font fallbacks. (The word setups does not appear in
mfonts, and fallback appears once. In the MKIV font manual setups
appears once and fallback thrice. None provide your answer.)

Font definition in ConTeXt allows extreme degrees of indirection. There
is a lot of flexibility that follows from this. By defining synonyms
such as serif and serifbold and using these in the document, the
document can be written independently of the actual fonts used. The
names are to some degree arbitrary, but used conventionally. There is
nothing stopping you from placing a sans font at the end of a chain of
serif references.

Setups are at their simplest a way to bundle other commands for reuse.
They also provide a namespace mechanism and a mechanism for group
setting and resetting of values.

The ConTeXt source file type-fbk.mkiv (and undoubtedly something similar
for MKII) defines a set of font name synonyms in a font:fallback:
namespace that is useful for gracefully substituting one font for
another when required, as when the document calls for a bold italic but
the font in use does not have that style. You can leave this out, or
define your own fallback hierarchy if you wish.

So, the first part of the typescript above defines ezrasil as a synonym
for the serif face and associates it with the file sileot and certain
otf features labeled hebrew. The file naming and search mechanism are
well described in the manuals. The setups brings in the standard set of
substitutions that will be applied when the document calls for serif
styles that the specific font does not offer.

The second part of the typescript defines another synonym (confusingly
also ezrasil) for the typeface and includes in it only a roman face
definition. In a latin script there would likely be another
definetypeface for the sans face, another for the mono face, and a
fourth for the
