[O] Converting paragraph to plain lis

[marvin doyley]

Hi there,

Does anybody know how to convert a paragraph to a plain list, and vice versa. For example, I would like to convert 

Lorem ipsum dolor sit amet, consectetur adipiscing elit. Suspendisse viverra consectetur euismod. Donec non tempor turpis. 

to 

1. Lorem ipsum dolor sit amet, consectetur adipiscing elit. 

 2.  Suspendisse viverra consectetur euismod.

3.  Donec non tempor turpis. 

In one key stroke, this would speed up my brain storming process.

Thanks,

M
