Script to search for Borders and Shading

Looking through the new API documentation at https://www.indesignjs.de/extendscriptAPI/indesign-latest/#FindTextPreference.html (thanks, Gregor!), I can indeed find nothing related to paragraph shading and borders in the FindTextPreferences.

So while we await for Adobe to catch up with this, it seems to me there is no other option than the old, painfully slow Loop Over All Paragraphs and Test Them One By One approach. "Testing all" is my least favourite workaround in the entire DOM because this value of "all" doesn't always mean "all of everything that I want here", and different approaches lead to different values for "all"... Plus, there is not a single 'best' approach that catches 'everything', 'most', or, indeed, 'anything useful at all'.

Each paragraph needs a bit of testing, too: first, of course, the property paragraphShadingOn -- if this is off then the answer is "no". However, if it is on, you still need to test if the fill is not [None] or the background color, if its fill tint is not 0%, and optionally if it's set to Not Printing.

Although you can't directly search for the borders and shading properties using Find/Change, you can search for them if you have a paragraph style applied. Using Find/Change, click on the "specify attributes to find" button in the Find Format section and choose the style that is applied. Then you can replace it in the Change Format section.
