Cool KDE Plasma trick: [Meta] + [v]
You know how you can use [Ctrl] + [v] to paste in place the last thing you copied to the clipboard, right?
A cool and productive-enhancing variant of that available in #KDE 's #Plasma desktop is that, when copying and pasting a lot of different things, you can hold down the [Meta] (“Windows”) key and hit [v], and a list of all the elements available on the clipboard will pop up so you can choose what to paste next.
Cool! No need for separate clipboard manager (unless you need more advanced features).
