Displaying verse numbers within a verse block

[Juan Manuel Macías]

Hi,

One of the many, many things where I use Org Mode is my Spanish translation of 
Homer's
Odyssey (work in progress). To avoid getting lost inside each Book, I wrote 
this little
code that helps me navigate through the verses, displaying in the margin 
(within a verse
block) the verse numbers in sequence of 5 (not counting the empty lines), or 
allowing
me to jump to a certain verse number.

I've uploaded the code to GitLab in case it could be useful to anyone who also 
has to work
with long runs of verses (hundreds, thousands...). Of course, this is something 
I wrote for
my own work, and I'm not a professional programmer either, so the code can be 
improved for
sure ;-)
