yank and append line relative to the current one

Question

I've enabled the relativenumbers in Vim. I would like to automate the following operation.

ma(number)(j|k)yy`a(p|P)

that is to say:

• mark the curr position in 'a'
• move up or down by 'number' lines
• yank current line
• jump back to position 'a'
• put line up or down

I'm looking for an easier way to perform the same. Is there one?

Thanks.

Answer 1

I guess I found the right way to do it with

:.(+|-)(number)y

for example

:.-3y

yanks 3 lines above.
