# Matter of Sorting element - What is Custom Sort?

I am investigating this Sort node in Animation Nodes. I found it to be confusing especially with Custom sort and Key List. I cannot guess what this is for.

Is there a documentation or can anyone help me to understand this Sort node a little better.

NOTE: Btw, I think the sorting of Text Sequence Script in VSE has issue. I have it happening on my latest live noding video.

Thanks.

Key - a key for a custom sort, which can be written as an expression using the attributes of your list element e. For example, you can enter e.location.x as as a Key to sort the list of objects based on their x location.
