I've used countless browser shortcuts over the years, but Ctrl+Shift+D is still my favorite
This How-To Geek piece by Tony Phillips is a personal case for Ctrl+Shift+D, the shortcut that saves every tab in the current browser window into a named bookmark folder so the window can be closed and later restored with "Open all." It is careful about limits that matter in practice: the shortcut stores URLs rather than page state (scroll position and unsaved form data are lost), it applies only to the window in focus, and some web apps or Chrome DevTools claim the key combination. The article is useful for anyone looking for a quick way to clear a cluttered browser without losing their research.
