Keyboard shortcuts for Accept/Reject

[andrewpareles]

Users should be able to accept and reject a change just using the keyboard, without moving the mouse.

I think the logic should look like this, but open to discussion:

1. if the user's mouse is on screen, pressing the YES/NO shortcut should accept/reject the closest diff to the mouse.
2. if the user's mouse is not on screen, pressing YES/NO shortcut should accept/reject the closest diff to the user's selection.

We should indicate which diff a YES/NO shortcut is about to change visually, maybe by only showing Accept|Reject on one diff.

Happy to take suggestions on what the keys should be.

Ctrl + Enter
Ctrl + Backspace

I now think the typical workflow is to accept/reject a few of the changes, and then accept or reject all after that. Sequential keyboard suggestions can interrupt this workflow, so I'm not going to worry about this issue for now.
