The LaTeX snippets for sections, when they contain a label, look like this:
\section{${1:section name}}\label{sec:${2:${1/(\w+)|\W+/(?1:\L$0:)/ g}}}
Somehow (I don't get the syntax for this yet)
The feature used is transformations [1].
As for the (?1:\L$0:): \L is a case folding [2] and the parenthesis is a condition [3].
the $2 part strips non-word characters from $1. Is it also possible to do transformations like replacing umlauts äöü with aou?
Not without stating each transformation explicitly and making the snippet even more cryptic.
