How do I paste a column of text after a different column of text in Vim?

Question

I have two columns full of text, and I want to get them side-by-side. For example, I have

abc
def
ghi

and

123
456
789
         


        

Answer 1

You have:

abc
def
ghi

123
456
789

Move your cursor onto the a. Then CTRL+V, and move your cursor to i. Press y.

Next, add a space after the 3 character, and press p.

Done.
