Answer 1

If you don't mind the semi-manual process, you can start at the first line and repeat the following key combination until you reach the end of the document (you get very fast at this)

Ctrl + D Down Down

This duplicates the current line, then moves down twice (to the line following the newly duplicated one).

If you have a large document, you can record this once as a macro (see the Macro menu), then use either Ctrl + Shift + P (Playback) repeatedly -- you can just hold those keys down. Or use the Macro option "Run a Macro Multiple Times..."

Answer 2

Highlight the desired code and press Ctrl+D. Don't highlight if you want to duplicate just the current line.

Answer 3

If you are using windows, I recommend writing an auto-hotkey (AHK) script to do this for you. This way, your special text-manipulation script will work in any IDE, not just notepad++. All you would have to do is copy your text example to the clipboard, and then execute an AHK script that reads data from the clipboard using the %clipboard% variable. Then you can load the clipboard with the results of your script and send a CTRL+V signal.

Answer 4

If you have the mouse cursor on the line you want to repeat, then you can use Ctrl-D shortcut to duplicate the line. Or you can use the same shortcut selecting multiple lines.

Answer 5

Open the search dialog box and write :-

Find:

^.*$

Replace:

$0\n$0
