Undo actions in text explorer

[#1]

Hello everyone,

When I process my terms in Text Explorer, I accidentally selected "add stop words" instead of recode for terms I want to keep. How can I undo the action and get these terms back to the list? My undo button is greyed out. 

Thanks!

Click the red triangle menu at the top of Text Explorer. Select Manage Stop Words.
