: Indesign: Find which pages apply certain masters I couldn't find this on my own. Using InDesign CC, I have set up 17 masters and +100 pages on a document. Hovering over a page will tell

@Ogunnowo857

Just save it in the indesign script folder as "Master Page Numbers.jsx" and run it with a document open.

Edit: I updated the script.

Now you just run the script and it will save/open a text file with the information about every master.

// Version 2
// gist.github.com/joonaspaakko/efc6eb11759965d54b20
// Tested in Mac - Indesign CC 2014

// Future improvements... mmaybe?
// - Adding colors to the text file. Just a little something something to help with the reading.

// Version 2
// Changelog:
// - Now prints out the page information about every single page in the document.
// - Removed the dialog, as it's useless now.
// - Due to the increased number of text printed out at once, it is now printed into a rtf file.

// If dialogs are your thing, you can still find the old version here:
