Why VIM set the default line navigation (jk) to navigate file开发者_StackOverflow中文版 line instead of screen line. Is there any use-case when this behavior is desirable?

---

You can change the behavior by adding these to your .vimrc:

nnoremap j gj
nnoremap k gk

---

Actually this is a desirable case particularly for blockwise selection and alignment of lines.

I particularly appreciate j and k to be consistent, which means ‘move to next file line, same column’.

Just consider that you can do this: by using CTRL-V and then j$.

Of course this is a completely random example and I never had any error accessing SO.
