+* Snippets
+  Mit Yasnippet lassen sich Templates definieren und mit einer Tastenkombination belegen.
+  Die Templates werden im Ordner /snippets/ jeweils unter einem Mode-spezifischen Ordner gespeichert.
+
+  Das Paket /yasnippet-snippets/ stellt eine Auswahl an Templates zur Verfügung. Mit /helm-c-yasnippet/ lassen sich die Snippets mit Helm durchsuchen und filtern.
