We need to repeat a-z throughout the file. Is there a setting for that?
No, that's now it works.
Also, I've found how to apply a character style to the footnote marker in the text, but I have not found how to do so in the footnote box.
Yes. You can nest a character style within the footnote paragraph style. I use an en space between the number and the footnote, so I apply superscript up to 1 en space with a character style called Footnote Reference.
Thanks, Barb. The nested style worked brilliantly. Too bad about the markers.
Great news on the nested style.
The only place i've ever seen or used alpha-numeric footnote numbering is in tables, where they always restart with each new table. And as you said, that would work if you start the numbering over on each page. You can always add a feature request here: Wishform - Adobe InDesign.
