Bug 380637 – app-misc/byobu with app-misc/screen - /etc/screenrc: termcapinfo xterm 'k1=\E[11~:k2=\E[12~:k3=\E[13~:k4=\E[14~' breaks F2-F4 functions keys

• Status: CONFIRMED
• Product: Gentoo Linux

The keys F2-F4 in byobu are disfunction in Gentoo.

I found the reason and a fix.  Appearently the section 
XTERM TWEAKS in /etc/screenrc does something to these keys via

  termcapinfo xterm 'k1=\E[11~:k2=\E[12~:k3=\E[13~:k4=\E[14~'

Replacing that with 

termcapinfo xterm 'k1=\EOP:k2=\EOQ:k3=\EOR:k4=\EOS'

fixed it.

It might also work properly if you simply deleted the line.

in /etc/screenrc , commenting out 

#  termcapinfo xterm* 'k1=\E[11~:k2=\E[12~:k3=\E[13~:k4=\E[14~'

seems to have fixed it -- word of warning is that this is strictly a console-only install as of now and I don't have xterm
