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.
It's a configurable option in Klipper (which is the process that's handling the clipboard in this video). You can access klipper in your system tray and if you right click on it one of the options lets you open up the settings (it's also somewhere in system settings I think but I always just get there via the system tray icon).
You can also configure how many entries it'll remember, whether it should pop up at the mouse cursor position, and set up regular expressions to recognize certain types of text (e.g. URLs) to perform specific actions.
