What does count() =1 represent (got a bit confused about jeni's explanation)
"and
count(. | .....) =1
id the currently selected viewdata is that first element.
so
"
Just to be clear, am i right in saying that "viewentry{key('ve-by-firstocc',
substring(entrydata[3]/text,1,1))[1]]" selects the first of each group of
viewentries with the same key (including groups which only have one
viewentry in it)?

No it selects the first (in document order) viewentry with each key
value (even if that key value is not repeated).
See any description of muenchian grouping, eg Jeni's site.
<xsl:for-each select="viewentry
that selects all viewentries then
key('ve-by-firstocc', substring(entrydata[3]/text,1,1))
selects al the entries with the same key,
so
key('ve-by-firstocc', substring(entrydata[3]/text,1,1))[1]
selects the first of that group
and
count(. | .....) =1
id the currently selected viewdata is that first element.
so
viewentry[....]
just selects the first entry in each group as teh predicate is false in
other case.
