I know I can use scrollback and copy/paste mode in byobu
to copy and paste text within the byobu windows.
This is achieved by
F7, (move with navigation keys), Space, (move again to highlight the text), enter
I can then paste that text into another window with
Ctrl+Insert
But that copy process doesn't copy the text from the screen to a buffer that can be used within other apps (not byobu), for example, pasting into stack overflow.
Any selection made with the mouse or in scrollback mode doesn not remain highlighted for a right click copy
and there is no right click popup anyway.
How can I copy what's on the screen in byobu
to paste into an external app?
