The new Subscribe in Unread share sheet extension has full hardware keyboard navigation and several keyboard shortcuts. Share sheet extensions do not have the keyboard shortcuts windows that apps have, but these keyboard shortcuts are available in the share sheet extension:

  • Press delete to unsubscribe from the selected feed.
  • Press command-c to copy a link to the selected feed.
  • When a row representing a folder, smart stream, or tag is selected, press return to toggle the switch.
  • When editing a subscription, press command-s, command-shift-d, or command-return to save the subscription.
  • When editing a subscription, press command-w to cancel. When on a list of feeds, press command-w to dismiss the share sheet extension.
