I installed Klipper, but I don't get it to work, and I don't know how it works.
Where can I find a users manual?
It seems klipper is gone (kf5/plasma) at least I can't find it in dbus or ps. I used to do qdbus-qt4 org.kde.klipper /klipper setClipboardContents "$(</dev/stdin)" > /dev/null to put things on the clipboard. what's the new magic for this?
Klipper's most useful, yet often overlooked, feature is so-called clipboard actions. It allows you to configure Klipper to run user-defined actions on specific types of clipboard contents.
