So I'm trying to get Calibre to use the first letter of a series name and if not that, the title of the book, only the help docs are archaic to understand and don't provide enough examples.

I found this:
{#series:'ifempty($, field('#genre'))'}

But I'm not using metadata at all, just 'series' or if empty 'title'
Which get's me:
{series:'ifempty($, field("title"))'}/{series} [{series_index}] - {title} ({author})
BUT... where do I put in the '.1' for only the series or title letter.
