Right. I knew its behavior, but can't remember whether I have heard this name before.

Good to know. I used to use local variables but was not sure whether they were to be preferred within calibre or not.

The good old "WITH" statement
Yes, I was looking to something similar, but was to lazy to RTFM (I do just occasionally some small coding effort within calibre, when the need arises that is)
Well the Template Catalog Plugin seems interesting (I had indeed asked myself how to control all those templates defined at various places) but this might help a lot.
Perhaps now a description about the do's and don't's of template creation, anybody?
