Home/End keys not working on a urxvt terminal under mosh

[achernya]

I don't think mosh does any keycode translations at all. From my read of https://github.com/mobile-shell/mosh/blob/1105d481bb9143dad43adf768f58da7b029fd39c/src/terminal/terminaldisplayinit.cc the capability inspection doesn't do anything with keycode translations.

You are right that mosh does not do any keycode translation. I can use showkey -a to verify that the keycodes of Home are identical on both local and remote boxes.

It confused me. Since mosh now uses TERM=xterm internally, how can it handle different term setups without any such translation?

I believe the answer is "it doesn't". I'm actually a bit unsure why we haven't run into this before, because I use mosh regularly from rxvt-unicode-256color myself, and have never noticed an issue.

Also, there is something interesting about this issue. Home/End keys won't work under the shell command line, but they work in both vim and emacs. Not sure why both vim and emacs can process them properly.

The 2 keys also work fine in tmux sessions, but not outside of it.
