Forum Post: Trados Studio: All segments confirmed mystery: Found a potential reason

From time to time some users report that all segments got confirmed and they don't know why. Well, the same happened to me today. In a document with several segments unconfirmed I did confirm a segment and all unconfirmed segments got confirmed in one go. What happened? I pressed the shortcut which I use to confirm and go to the next unconfirmed segment. But when I did so, TWO segments were selected. But not in the way which would allow to merge them. No, simply selected like lines in Word, so the background was not yellow (merging is active), but black. A simple segment selection using SHIFT and arrows. And in this very situation all segments got confirmed. So this is a potential answer to how this can happen.
