If you want to stay with xterm-256color in tmux for some reason - use arch solution with inputrc. I tested it in tmux with rxvt, ruby irb, python, lua and home/end keys are ok. Probably every readline app will be ok.

From the arch wiki:

First things first:

do not set $TERM manually - let the terminal do it.

Many command line applications use the Readline library to read input. So properly configuring Readline can fix Home and End in many cases.

the default /etc/inputrc file does not include a mapping for home/end keys.

To check what the emitted escape sequence for these keys is:

1. Ctrl + V
2. Home
3. Spacebar
4. Ctrl + V
5. End

this will probably print: $ ^[[1~ ^[[4~. So you have to add a mapping for these sequences to your inputrc (/etc/inputrc to be globally, or only for your user ~/.inputrc):

"\e[1~": beginning-of-line
"\e[4~": end-of-line
