I have no idea how long this has been a thing, and maybe every clipboard works that way, not just Plasma, and I never realized it. It also lets you do things like Rt-click on it and do the regular operations like Search in Firefox. Spaces aren’t preserved unless you specifically select them but search engines seem to be able to sort out the words usually.
I post this in case you haven’t been part of the 10,000 this day already, like me.
Edit: seems to work in Firefox and LibreOffice, but not Kate or Okular. I’d love to see this as a general feature, it’s handy as heck.
I am making an assumption that you grew up with something like an iPad. This isn’t your fault, you had no reason to learn it before. Now that you have a need to do these things, you figured it out by accident just through exposure.

Haha. Well, my first computer was an Apple II, if that counts…
Are you talking about selecting multiple unconnected sections of text, so that they are highlighted at the same time? I think that’s a Firefox feature.
Or are you talking about selecting something and then something else, so that only the last thing is highlighted, and finding both selections listed as separate items in KDE’s clipboard manager?
Talking about the first. Seems to work in Libreoffice as well, but not Kate and Konsole. So it’s definitely app specific, not a KDE thing.
Firefox and LibreOffice aren’t part of KDE, but Kate and Okular are. So the fact only the former two support this feature indicates it’s not from KDE. This should probably be supported by KDE though (or by Qt? perhaps this should be done on the toolkit level rather than on the application level). Holding ctrl to multi-select is standard behaviour in a lot of applications and is quite useful. For what it’s worth, Krita does support this, but you need to hold shift instead of ctrl.
