emacs: Orgmode, how to make a list from a block of lines

Question

Is there a way to covert such block of lines

line1  
line2 
linen

into

1. line1
2. line2
n. linen

Using Emac

Answer 1

the shortest way I know of is: highlight the lines, including their newline character,

line1
line2
line3

Then execute M-x org-ctrl-c-minus (press C-c -) and you will get

- line1  
- line2 
- line3

Then run M-x org-shiftright (press ) twice and you get the desired

1. line1  
2. line2 
3. line3
