Mark mail as read
Bring back keyboard shortcuts (example, "k" for marking selected emails as read).
Dan McVicker commented
Is there even a delete shortcut? That's my number one use of email, deleting it
Toni K commented
Yes, pls. Plain k should be enough for mark as read. Just replace the pop-up telling that "the new shortcut is shift+k" with the "mark as read" functionality. Why would you even write a popup message instead of keeping the old shortcut :p

It's Shift + K now
