[Orgmode] Custom agenda views

[Dave C. Nelson]

I'm playing around with org mode and while it works mostly the way I
want, I have something I'm trying to do and so far I've failed. I should
mention that I'm not much of a lisp programmer, so it might be my lack
of knowledge here.

What I want is to have an agenda view like the default agenda view one
gets with c-a a, but "narrowed" so that only a subset of todo items
show. For example, when I'm at work, I want to narrow the agenda view so
that it only shows todo items related to work. 

I've read through the manual, the past list postings, etc. and I just
can't seem to come up with an org-agenda-custom-command that does this
(I assume this is the way to accomplilsh this). Is it possible? Would
someone please give me a hint?
