Vim has a lot of key commands to quickly working with blocks of text so it is a bit more nuanced than that.

For example, to copy 3 lines from the cursor position and paste them 5 lines earlier:

3Y :-5 p

(and there are faster ways, some people are wizards)

I also do relative numbering in my vim (I have the current line labelled as 0, the line above it -1, etc) so that I can move around relative to the cursor without having to count lines. You can also do absolute numbering but I find that tedious when you have large files.

I know, I've been using vim pretty exclusively for the last 15 years or so.
