Sometimes we find it confusing. ;-)  I think it's a class of terminology
between the docs and the widget.  imagedefaults uses McIDAS language
(group/descr) and the widget uses dataset/image data type.

There are three widgets in the chooser that make up the server:group/descr
triad:

Server:  - the server portion
Dataset: - the group portion
Image Data Type:  - the descriptor

So, if you have adde.ucar.edu:RTIMAGES/GE-IR  you would put adde.ucar.edu
for the Server widget, RTIMAGES for the Dataset widget and select the
appropriate Image Data Type that corresponds to GE-IR.  Confusion in the
latter is further compounded by the fact that the widget shows the
descriptive name, so on adde.ucar.edu, GE-IR corresponds to 
GOES-East 10.7 um IR.  At least your datasets don't have descriptive
names. ;-)

Any of server:group/descr fields are optional.  This allows you some
flexibility so you can set up redundant servers with the same group/descr
data and all will get the same default values.  not having the server
is equivalent to *:EUM_AD/M8.  When we create case studies, we may change
the group name (e.g. RTIMAGES to CASE1) but keep the descriptor the same so
we can have */GE-IR which would apply to all groups that have a descriptor
of GE-IR (e.g. RTIMAGES/GE-IR or CASE1/GE-IR).

Since this is the first pass at this page, we'd welcome suggestions for
improvement.  Hopefully the explanation above will help in the mean time.

I'm off to camp with the family today, so have a great weekend!
