What are bulk actions?
Bulk actions let you select up to 50 articles in a feed, folder or other article list and act on all of them at once: mark them read or unread, tag them, email, print or export them, open them in tabs or turn them into an Intelligence report. You start them with the Bulk actions button in the header of the article list.
Select mode
The Bulk actions button, a checkbox icon in the header, shows in List, Card and Magazine view on a computer, and in Reading list in Read later and Archive. In Read later and Archive you can also tick the checkbox that appears on an article's picture when you hover over it. In Column view and on phones, the header's ⋯ menu has Enable select mode instead, and Expanded view has no select mode. Once it's on, every article gets a checkbox: click the checkbox or the article to select it, and Shift+click to select everything between it and the last article you picked, up to 50 at a time. The actions bar appears at the top of the reading panel, at the bottom on phones, and counts the selected articles. The X in the bar or Esc clears the selection. A second Esc leaves select mode.
