Listing (Indexing_?)

I am sorry for this begginer’s question.

A few weeks ago, when I selected several files in my database, I got a text with selected titles list in the database in unexplained one action.
As same as >script>export>listing…> and import it.

Now I have forgotten how I did.
Could you tell me please?


I know now!

An option script “Create Index for Selected Items” from DEVONacademy.

Thank you.
