No More Gmail Sneak Peek

Gmail had a cool Labs feature that allowed you to read messages without opening them. Message Sneak Peek displayed the first sentences from a message when you right-clicked it. You could use keyboard shortcuts to navigate to the previous or to the next message, so this was a great to quickly read messages.

Here's a screenshot from 2010, when this feature was launched:

The Labs experiment is no longer available and now Gmail has a contextual menu that shows features like "move to inbox", "archive", "delete", "mark as read/unread", "move to tab" (for inbox messages). You can select multiple messages, right click and use one of the features that were also included in the Gmail toolbar.
