I do not know how the file explorer in Mac works. And I do not know where
a typical installation installs context in Mac. Suppose it is installed in
/usr/local/texlive/2007.
The all the context files will be in
/usr/local/texlive/2007/texmf-dist/tex/context/base
Basically, INSTALL-LOCATION/texmf or INTSTALL-LOCATION/texmf-dist or
INSTALL-LOCATION/texmf-context and then tex/context/base directory inside
it.

The basic idea is to first understand how a particular command is defined.
Here is what I do: go to tex/context/base directory and search (by any
means, I use grep, but you can as well use any program that allows you to
search inside files) for the command you are looking for: in this case
footnote. You may either get a huge number of results, or a few results.
If you get a few results, check them manually, to see which file defines a
command. A command is usually defined as
\def\commandname
or (rarely)
\edef\commandname
\xdef\commandname
\gdef\commandname
or (more frequently)
\define<something>[\v!commandname]
here <something> can be any text.
If your search gives a lot of results, you need to use a regular
expression to filter it to one of the above. I don't know if Finder in Mac
allows for regular expressions.

I know what you mean here :)

As far as syntax goes, just ignore those funny \c! \v! thingies. Then you
can read them as
[location=page,
way=bypart,
sectionnumber=no,
conversion=,
rule=on,
[etc..]
These mean, that
i) Footnotes should be located per page.
ii) They should be numbered per part. That is, if you start a new part,
footnote numbering restarts.
iii) I don't know what sectionnumber does, so I ignore it.
iv) The number should not be converted to anything. You can convert them
to characters, Characters, romannumerals, Romannumberals, etc.
v) The footnotes should be proceeded by a rule, etc.
You see, most of the keys for all environments take command key-value
options. If they are explained in the manual, then great; if they are not,
start guessing what they mean, and experiment if you get the right
result. Try three times, and if you don't get hit the right answer, ask on
the mailing list. Hopefully, someone will reply. Then you know, what a
particular option does for *all environments*. If you don't get an answer,
well... then ask what you want to achieve, and hopefully someone will tell
you if it is possible or not.

I explained above how I started to understand these things. I am sure that
other people have different approaches. I do not understand how TeX works,
but reading ConTeXt sources are much easier than reading latex sources. I
started with LaTeX, and in LaTeX I could never manage to understand 80% of
the what was written in the sources. In ConTeXt, I can understand 50-60%,
that is what I meant my "easy".
