Scrolling through message edits

I'm thinking something where you can keep pressing the up button similar to how you already edit a message from selecting the message bar, but in the message edit, if you scroll to the top and press it again it goes to the NEXT message, etc. etc. so you can use the shortcuts for editing multiple messages. Similar to the way the chrome console and like anything else does it where the up works once you've reached the very end of the line / the point where pressing the up button wouldn't do anything anymore.
