Grep Styles On Off
Grep Styles are fantastic, but they can slow you down. InDesign will run the grep every time the text is composed, this can be a lot on long documents and this can take a long time.
The off button makes the grep expression invalid so it is not executed. The on button will reverse this.
We have tested the script with our long documents, please backup your documents before using it.
