Moving by line and not by sentence

Using macvim. Say I have one sentence which takes up 5 lines in the editor. And a second sentence which occupies th开发者_如何学编程e 5 next lines. Start with cursor on line 1. In normal mode, pressing j will take me to the next sentence (that is, line 6).

How to change this behavior to where pressing j will take me to line 2 (which is still part of the first sentence?). Or instead of using j, any other way to achieve this goal?

The actual problem is that the line (not sentence) is too long and it wraps to multiple display lines. The default movement with j and k will move the cursor in real lines, not display lines.

You can remap j and k in normal mode to do move in display lines:

nnoremap j gj
nnoremap k gk

(in your .vimrc).

j takes you to the next line. I think you have a terminology problem (“sentence” doesn't mean what you seem to think it means). If j doesn't take you to the next line on the screen, it's because the file contains a very long line (what you call a “sentence”) that is too wide to fit on the screen. If there is a very long line, it is displayed on several screen lines. Vim calls these “display lines”. The j command moves to the same position on the next file line; gj moves to the same column on the next screen line.
