i sometimes need to use the split window to show me 2 or 3 code chunks that are sequential, so that they scroll together.

i mean, not 3 different, distant parts of a document, but like one longer part of a document, where a core function with several recursions and nested loops is defined, in many lines, and i want to see them all.

usually i print them out and then inspect.

is there any editor to do this? maybe chocolat will?..
