I find that I can 'grok' about four lines. So if I have three lines to delete, I can just type 3dd and not get it wrong. But if I have ten lines to delete, I don't think of it as ten lines, and to be honest I type "shift mouse movement vd". What threw me off for a long time was trying to combine with j: it's `n+1`dj = `n`dd, and the former is almost never what I want. Since j is down I kept thinking I needed to use `jd`, and that isn't how it works. Sort of stuck with that for upward line delete, it's never intuitive to me to want to delete three lines up and express it as 2dk. I wish that D was backward, so it would pair with t/T and f/F, but it's an entirely different sort of deletion which I rarely need to combine with a motion. Even for what it does on its own, I use d$ out of habit. There must be a way to remap it, but one of my premises in using vim mode is that the skill transfers well, and changing any of the conventions fights against that.
