I tried to configure Spectacle, but I don’t get how to take a screenshot saving to clipboard without opening Spectacle.
In xfce4, you could just align Print key to “xfce4-screenshooter -f -m -c”, and this would save the screenshot directly to clipboard without opening xfce4-screenshooter plugin window.
Thanks for help and best regards.
Did you read the Spectacle documentation as provide by KDE? https://docs.kde.org/stable5/en/kdegraphics/spectacle/index.html
It gives in Chapter 2. Starting Spectacle a lot of information and it says that
will give the command line options (which is rather a standard way to get them explained).
And I guess it is possible to couple your beloved application to the PrintScrn key instead of Spectacle.
