Hi Scott,
Thank you for the great video tutorial. I learned a lot about this great program with invaluable tips and guidance.
Of course after the tutorial there are so many more questions that come to mind.
This is one of them; in the snippet below, which I copied numerous times from an example you provided that allows one to make a numbered list from a menu can you explain the various operators such as "len", "count" and is "i" an operator or something you had designated and I simply copied?

{note}Eye Colour{formmenu: name=Eye_Colour; multiple=yes; Brown; Grey; Black; Blue; Green}{endnote}
{if: len(Eye_Colour) > 0 and count(Eye_Colour) > 0; trim=yes}
The group's eye colour includes:{repeat: for i in seq(1, count(Eye_Colour))}
{=i}. {=Eye_Colour[i]}{endrepeat}{endif: trim=left}
