How to copy several lines from a buffer to another in Emacs?

Question

I have two buffers. I want to copy the line 2, 5, 9 and 10 in the first buffer to the second buffer(just append to the second buffer). Except copy and past one line at a time, is there any elegant way to do so?

Answer 1

You can use the command append-next-kill, bound to C-M-w, to add more text to the latest entry on the kill ring. Use it right before a M-w command, something like this:

• Mark and copy line 2: C-SPC, C-n, M-w
• Move to line 5
• Mark and append-copy it: C-SPC, C-n, C-M-w, M-w
• Move to line 9...

...and so on.

When you yank the text with C-y, you'll get the lines you selected and appended to the kill ring entry all together.
