Sorry for the delayed response! I’m currently looking into how this might be able to be done, yes. The problem is not specifically in the “jumping to next section” – that part is pretty easy; the problem is more in the related functions: copy to left, copy to right, use left in merge, and use right in merge. If we allow the “jump to next block” and “jump to previous block”, the expectation would be that we should allow “copy block to left”, “copy block to right”, “use left block in merge”, and “use right block in merge”. The merge functionality is much more complex.
While the old compare window did allow jumping forward and backward by blocks, it was severely limited in other functionality, and provided no method for merging. Neither the old compare window, nor this one, is designed to be a full compare and merge utility (there are a number of full free and commercial products out there to do this), but I’ll see what I can do to add whatever I can for this release.
