Today I learned about the copy command (alias t):
:[range]co[py] {address} *:co* *:copy*
Copy the lines given by [range] to below the line
given by {address}.
Let’s say we have a file like this:
1 line a
2 line b
3 line c
4 line d |
You are on line d (symbolized with the | as the cursor).
You want to copy from 1 to 3 (line a, line b, line c).
Type :1,3t., hit Enter and Vim will add the previous lines underneath the cursor.
t is a shortcut for the :copy command.
The . (dot) is for the current line. And 1,3 is the range you want to copy: from line 1 to 3.
The original tip (with relative line numbers) is from Mastering Vim.
I needed some more examples to understand the copy and the range in Vim, so I looked it up on Stackoverflow, too.
