How can I perform the same action on all results of a label/search in Gmail?
In Gmail, I have a bunch of messages under a label that I want to delete (basically all the "unread" messages).
I can filter for and select "unread" and then delete them, but it only applies to the first 25 items and I have hundreds I want to delete.
What I'd like to do is to apply a filter, select the matches, and delete all the matches even if they're not in the top 25.
Is there a way to do this?
