"Holding shift while starting an application temporarily disables restoring the app's saved state, such as opened windows and documents. To temporarily prevent an app from re-opening its documents and windows, hold the Shift key while you open the app." - Apple.
I had done a search in my computer and about 1400 documents appeared. I wanted to screenshot specific ones, so was sending about 800 documents to trash so I could screenshot those left before putting back the 800 documents. I must have hit a wrong button - instead of going to trash they all started opening. I force quit Word. Then I tried to open Word again, and as it always does, it started opening all the documents that had closed on force quit. I again force quit Word. The number of documents that opens automatically can be set in Preferences of Word, but I can't open Word at all in order to set the preferences without all of the documents opening. How can I open Word without all the documents opening?
