Is there any command to toggle enable auto text wrapping?

Question

By default, I think my vimrc setttings enable the auto-wrapping. However, sometimes, I would like to see text lines are not wrapped. Is there any command I toggle the text line wrapping enabled and disabled? This would avoid me to exit and to change settings.

Answer 1

I think what you want is:

:set wrap!

This will toggle line wrapping.

Answer 2

In your vimrc, create a function such as this:

:function ToggleWrap()
: if (&wrap == 1)
:   set nowrap
: else
:   set wrap
: endif
:endfunction

Then map a key (such as F9) to call this function, like so:

map <F9> :call ToggleWrap()<CR>
map! <F9> ^[:call ToggleWrap()<CR>

Whenever you press F9, it should toggle your wrapping on and off.
