FindChangeByList

> Do you know if there is any place that one could see the proper names to use for the formatting options

Not really. you have to be familiar with the object model. You could trawl through

https://www.indesignjs.de/extendscriptAPI/indesign-latest/#about.html

but that's pretty daunting for non-scripters. Easiest is to ask in this forum.

Nope. it's fillColor: "Black"

An alternative to FindChangeByList.jsx is this script:

The advantage of this one is that you use InDesign to define queries so that you don't have to look things up in the object model.

The script uses a side txt file (I think you got that part) and it explains how you should use it but doesn't cover the formatting options. Good thing is that the txt file is basically a set of javascript properties for the find and change GRE preferences that are passed to the F/C engine.

So all that you need to do is to add thos formatting options in both the find and change objects like this:

grep	{findWhat:"^",firstLineIndent:"0.5in"}	{changeTo:"\\t",firstLineIndent:0}	{includeFootnotes:true, includeMasterPages:true, includeHiddenLayers:true, wholeWord:false}	Replace 0,5in first line indented paragraphs by tabbed paragraphs.

Once you set the firstLineIndent property, you got the expected behavior.
