The secondary-selection is used when the cursor is in some focussed Recipient window, in order to grab some text (or whatever) from some Donor window (possibly the same window as the Recipient) and have that text pasted at the Recipient’s insertion-point (overwriting any primary-selection in the Recipient).
I’ve been using the “select copy + middle click paste” since the late 90s.
I find it useful for simple intra-document editing because you’re just using the mouse, no need to reach for the keyboard.
It can be combined with the traditional copy/paste, say you have your password in the clipboard but you need to also copy some part of a long ssh command. You can have both and paste them on the command line one after the other.
I know I’m a minority and this will eventually be dropped because it’s too confusing for the end users, man.
Yes, I get it. But I’ll miss it.
You’re describing the primary selection. The article’s about patching secondary selection back into gtk3 (c. 2015?). It’s ctrl+select followed by ctrl+middle to paste as yet another clipboard. This has the unique and useful property that neither selection nor paste changes the text cursor’s position.
A more in-depth look at secondary selection is in the embedded video which has it’s own write-up on https://www.cs.man.ac.uk/~lindsec/secondary.html
[I suspect primary-secondardy selection is not a confusion you have, but one a casual skip-the-article-direct-to-comments reader might have]
I assumed primary is ctrl-c/ctrl-v and secondary is select/middle-click. I’ve never come across this ctrl-middle-click, it does the same with and without the ctrl key.
I seen to recall reading something this week about a distro dropping middle click, so I probably conflated both issues and failed.
But you’re right, I did not read the fine article.
Nobody is removing it?…

Gnome can’t ship a config to disable secondary selection because there is no secondary selection.
Oh right, wayland.
Never even thought of that, but this is genious.
Maybe using ctrl for that is not the best decision, but I understand this was just a showcase. I wish this actually existed and was used in real desktop environments.
It’s in emacs! Using alt instead of ctrl https://www.gnu.org/software/emacs/manual/html_node/emacs/Secondary-Selection.html
Sounds terrible
Why’s that?
I am using Ubuntu 14.04LTS “Trusty Tahr”…
Wow that is ancient! Interresting feature, I wonder if it could be reimplemented as a wayland protocol, however I think some modern IDEs and some text editors have something similar nowadays.
