Copy and Paste in a column in Notepad++

1. Hold Alt+Shift+Arrow keys or Alt + mouse selection to select the rows you want to move.
   To quickly select several rows (lines), place the cursor at the beginning of the starting line, then hold Alt+Shift and click the end of the last line - make sure the selection covers the entire length of all selected lines.
2. Press Ctrl+X to cut the selected text
3. Place the cursor in the column you want to paste to and press Ctrl+V.

EDIT: Please note that the content you want to paste needs to come from Notepad++, copied using Column Mode (thanks to user @Dominique in the comments).

This will provide the result you want.
