Add variants of copy-right, copy-left buttons to copy-right-and-go-to-next-diff, etc.

It would often speed up my work comparing files if you had an additional pair of buttons in the center of the diff bar just to the outside of the existing copy-right and copy-left buttons, which performed the copy-right/left operation AND also the move to next diff operation in one button click action.

As things stand now, I usually have to press copy-right/left, then move my mouse 8+" to get to the next/prev diff buttons, or manually scroll via the mouse, not as efficient.

Should the copy-right and copy-left buttons be changed to also move to the next diff? Kind of feels like that might be a more intuitive experience.
