I love Byobu and hate the Midnight Commander (MC), especially because MC collides with Byobu's keybindings. But quite often I split a Byobu window vertically and wished I could simply copy a file from one split to the other as I can do with MC. Something like this:
cp file.txt $b1
Where $b1 would be a variable pointing to the location where the split 1 currently is. I could try adding some trick to each shell (for instance, using an alias for the cd command, saving the current location to a file, reading it somehow on another shell), but invariably a shell session would need to find its own split number. Is this possible?
