Yes exactly - Hashes denote 'sections' in eno!
In the language design phase this was heavily inspired by markdown, because of the already widely familiar concept of 'headings' - I collected feedback from users that (although they showed considerable anxiety given the prospect that they were to use text files to edit their content in the future instead of a fancy web interface) they found working with markdown (quote) "super easy", so markdown was therefore an influential factor for some aspects of the language design. :)
