Yes, but that’s probably not relevant to the OP’s situation.

I believe @RARgames is relying on a side effect: if your caret is on a line that’s shorter than the screen-width (or than the first vertical edge setting), then Ctrl+I’s “Split Lines” actions will select the whole line, split it into one line, and finish with the whole line is suggested.

If @RARgames had instead tried on a line that goes beyond the first vertical edge setting or screen width, the Ctrl+I would have actually split the lines into 2 or more lines, and ended with all N of those lines selected. To continue with that modified macro invites the danger of accidentally splitting long lines in the future.

Further, doing the Ctrl+I first would only do anything for @RARgames if there was a stream selection that went from the middle of one line to the middle of some other line (or from the beginning of one line to the end of another without selecting the EOL sequence).

@RARgames said,

it would be better to return to a previous cursor placement

Macros don’t have variables/memory, so they have no place to track such a thing. As our Notepad++ Automation FAQ says, if you need something with “memory”, you need to switch from Macros to a true programming language, like one of the scripting plugins (PythonScript Plugin being the most-frequently mentioned, here). With a scripting plugin, you could put the full logic: "look at the active stream selection; if the start of the selection is not at the start of the line, move it to the start of the line; if the end of the selection is not after the EOL sequence (or not at EOF if the end of the last line doesn’t have EOL)

press Ctrl+I to select whole lines, but without last new line char

By default Ctrl+i is assigned to the Split Lines command, and I don’t see how that is helpful here??

So I replaced it with slightly different macro:

• press Ctrl+I to select whole lines, but without last new line char
• press Shift+Right Arrow to add this new line char (there is an issue if there is no new line[end of the file] - same with previous macro)
• press Ctrl+D to duplicate
• press `Home to return to the line start (I don’t like this - it would be better to return to a previous cursor placement)

It works better for me, but still has some issues.

Yes, I think @guy038’s post should be more explicit about “assuming Ctrl+D is mapped to SCI_SELECTIONDUPLICATE (which is the default mapping)”, because this discussion was begun with someone wanting to redefine the Ctrl+D behavior.

Also, @guy038 said,

However if you do a seven-lines RECTANGULAR selection , at the beginning and, then, hit the End key, now, clicking several times on the Ctrl + D shortcut just add one copy of each line, at a time !

… that is only true if Preferences > Editing 2 > ☑ Enable Column Selection to Multi-Editing is checkmarked. If it is not checkmarked, then when you hit END, it leaves column-mode or multi-edit selection mode, and the caret just moves to the end of what used to be the rectangle. (It took me a while to figure this out, because I could replicate all the other behavior mentioned, but I was just not getting the one-copy-of-the-line behavior described.)

For any such discussion, Preference and Shortcut Mapper states can be quite important to the discussion.

did you know these particularities when you invoke the Ctrl + D shortcut

I think it might be poor to talk in terms of Ctrl+d, because if memory serves, this shortcut has had some inconsistency (in what command it is tied to) in Notepad++'s history.

BTW, did you know these particularities when you invoke the Ctrl + D shortcut …

Let’s start with this INPUT text :

Now, do a normal selection of all this text and use the Ctrl + D shortcut. We get the usual new text , below :

If, instead of a stream selection, we use a zero-length RECTANGULAR selection, whatever its location, among all allowed ones. Then, after a Ctrl + D operation, we get this text :

And, if you hit the Ctrl + D shortcut again, every block of two lines is, itself, duplicated. Just as expected !

However if you do a seven-lines RECTANGULAR selection , at the beginning and, then, hit the End key, now, clicking several times on the Ctrl + D shortcut just add one copy of each line, at a time !

Of course, if we select a non-zero RECTANGULAR selection of these seven INPUT lines, we get, as expected, all text selected being written twice !

For instance, let’s do a four chars RECTANGULAR selection, beginning right before the word an of the first line and ending at string hort of the seventh line

After using the Ctrl + D shortcut, the OUTPUT text becomes :

For the record :

• If you do a normal selection of one line only, without its like-break, the text of all this line is simply added right after, on the same line

• If you do a normal selection of one line only, with its line-break, all the text and its like break is duplicated on the line below

• the original selection needs to be a stream selection; if it is a column block selection it will not work
• the original selection needs to contain a line ending (or more than one); if the selection is only on a single line it will not work

EDIT: Also thanks for the macro suggestion!

Sorry, I didn’t notice in your original statement that the selection went across multiple lines.

No single Scintilla command will do exactly what you want. But you could record Alan’s sequence as a macro, and assign that macro to a keyboard shortcut.

There is no built-in way to achieve: “Duplicate all lines touched by the selection”, AFAIK.
Well…unless you select the lines in-full and then do SCI_SELECTIONDUPLICATE.
But if you just want to partially select some lines and have it work on the full lines…then no.

A workaround, where you start with partially selected line(s):

• press Tab to indent the lines (lines become fully-selected)
• press Shift+Tab to dedent the lines (lines are still fully-selected)
• now do SCI_SELECTIONDUPLICATE

I want to find something that allows me to press Ctrl+D to duplicate whole lines.

Then give your preferred keyboard shortcut to SCI_LINEDUPLICATE instead – it defaults to nothing, as shown below, but you can assign whatever shortcut you want to it (and remove the shortcut from SCI_SELECTIONDUPLICATE if you don’t ever want to use the fancier “duplicate selection, unless there is no selection in which case duplicate the whole line”)

and I want to find something that allows me to press Ctrl+D to duplicate whole lines.

When I duplicate

That statement is vague.
What are you doing to “duplicate”?
