@NippurDeLagash: “just position the cursor” is the very thing I shouldn’t have to do. It’s already on the line!

@Gogo-Neatza The plug-in manager infinitely insisted it needed updating.
Once I ignored it, a couple of attempts at installing this plug-in finally worked.
It appears to add two menu entries… I assumed they’d be checked entries enabling the behaviour but they’re the commands…

So then I read @Scott-Sumner’s links which all mention the plug-in too and finally a dozen steps that I need to follow to finally get this basic text editor functionality:
https://bitbucket.org/zastrowm/notepad-visualstudiolinecopy
So now I can join the throng of people who can get on with their work sensibly.

I do, however, remain in disbelief that a user should have to go to the lengths I have to simply cut and copy lines efficiently! I’ve been ignoring Notepad++ since 2004 because of this shortfall (and our fixed-width fonts not being fixed width), which leads me to ask the community again:

Would it hurt to fill that hole?

I did read @Kaley-Goode’s message, as was fully aware about the need of no text is selected. That’s why I answered: Just position the cursor, i.e. place the cursor over the line, exactly the same way you do under Visual Studio. There is no need to select anything.

And yes, I assumed (wrongly) that the lines were all in the same file.

This has been much discussed over a long period of time; here are some references:

I’m not really one for thinking that Notepad++ should be a clone of Visual Studio (shudder!), but I do agree that this specific thing makes a great deal of sense–why not have a keystroke that would otherwise do nothing…do something useful and sensible? However, since we haven’t seen it yet (natively) in Notepad++, I’ve got to question whether it will ever be done. Thus, I’d encourage those interested in having the functionality pursue one of the alternative methods (see links above) for achieving it. I did…and then I stopped thinking about it. :-D

This behavior is a “option”! Lowest commonly behavior are “Ctrl-c” & “Ctrl-x” do pure copying/cutting of selectet objects!

@Udo-Fuerhoff: Sorry for upsetting you with my ridiculous suggestion.
I don’t understand what’s unreasonable when Ctrl-C and Ctrl-X currently do nothing.
I’d be perfectly happy for it to be an option in Notepad++ too.

@NippurDeLagash: I wasn’t clear: I rearrange lines between editors: so I cut or copy a line from one editor and paste to another.

Ctrl-X in one, Ctrl-V in the other. A lot. It’s great. Easy. Until I try notepad++. Then it isn’t.
Ctrl-L is a long way when your right hand is on the mouse.
Ctrl-X then becomes a quick way to delete lines too.
