Is there a way to move by screen lines in vim?

Question

When editing files in vim, it is a small annoyance that when I move lines with j and k, it moves by file lines, rather than screen lines like other editors. With my own files, I can deal with this by automatically wrapping to a certain length in the vim options, but this is no good for files from others. Is there a vim command to either temporarily toggle the treatment of lines to screen lines, or alternate commands for moving that use screen lines?

Answer 1

You can move around the screen lines by using g in front of the commands:

gj
gk
g$
g0
g^

You can also map the original commands to the g commands like this:

:map j gj

j moves by screen lines now.
