Hi Marco,

what I meant was

- starting, say xterm or rxvt and then mc: what does shift+f5
- then closing mc and starting tmux in the xterm or rxvt-window and then 
checking, what shift+f5 does... does the behavior change?
- i sometimes watch some inheriting, so if the behavior is different in 
these cases it must be a terminal programs problem...

btw did you try the "keylerning" for mc in tmux (backup ~/.config/mc/ini 
first), did the shift+fn keys work there?
