Pretty sure most of you already know this but for those who don’t: you have two clipboards in Linux. One is the traditional clipboard where you copy with control c and paste with control v. The other one is when you highlight text and use the mouse middle click to paste text.
More details here.
Windows and KDE Plasma both have CMD + V to show a list of all things that have been copied. So I always just do Ctrl + C, Ctrl + C, Ctrl + V, CMD + V -> down arrow -> enter. Though on KDE Plasma you will need another Ctrl + V to actually do the pasting after you have selected the value to paste, whereas on Windows selecting the value also pastes it. But the workflows are very similar.
