			When running an application inside a root-full X11 session, within XWayland for example, it may not be able to access Wayland clipboard directly (pasting doesn't work). The below commands require packages, which, on ArchLinux are named "xclip" and "wl-clipboard".

			bash -c "xclip -o -d ":2" -selection "clipboard" \| wl-copy"
			I placed the command lines inside a call to bash, as these were added to custom keyboard shortcuts, for my GNOME desktop settings.
