Hope this helps and is what you are asking. . .
The revision tool is in the active or live listings, there is drop down box that says DESCRIPTION click it and new window will show up. There should be 2 boxes. You need to put exact sentence or sentences you want removed in the top box. If you want nothing put in its place you leave 2nd box blank. If you want something to replace what you took out you will need to put that in second box. (IF, it does not work do not drive yourself nuts - as mine did not work on a recent change ebay had us make and I had to change 1500 listings manually.) I just do not want you spending hours trying to make it work like I did and waste your time.
Please remember. . . if you change ACTIVE listings they will change on ebay, however, it does not change your original saved template. It will only make the ebay live listing.
so you still have to go in and change twice if you want your original template updated.
