The script displays which text variables (of the type Custom Text) have been defined in the active document and shows their contents. It can be also be used to change the contents of any text variable. I use it in master documents for journals to change variables for volume and issue numbers, publication dates, etc.
The script displays the dialog shown here. The names of the text variables defined in the document are shown in the first column as field labels, their contents in the fields.

To change the contents of any variables, just enter the new values in the text fields. When you're done, press OK.
