Easily cycle through the transaction entries

There should be a keyboard shortcut (I was thinking about Cmd-{right arrow}) to select the next entry in the selected transaction

I'm not sure about this one anymore. The only reason for this feature to exist is, I think, to change the transfer of the other entry. And it is likely that there are more entry you want to change this way in the account (like in Imbalance). But once you change the transfer of the bound entry, you can't go back to the account you were cleaning up. I think the Drag and Drop of entries will be a better workflow for what I wanted to do in my use case, which was to merge 2 expense accounts.

Ok, I really am not sure at all about this because I have no use case for it, but I still think the concept has some potential, I'd keep it around (in Future)
