As per the subj, I'm looking for a way to exclude one of the split windows in vimdiff yet still compare the other 2+ windows (with colors and all that jazz).
A use case: a file with keys and 2 files with values (same number of lines). I want to compare only the values but have the keys in the view still (without having to open two terminals). This would also allow for parallel scrolling, which is a feature of vimdiff.
