Several keybindings don't work over SSH+Byobu (Shift+arrows, Ctrl+arrows)

[csolisr]

Description of the problem or steps to reproduce

When using SSH on a server configured to run Byobu, attempting to use Ctrl or Shift plus the arrow keys outputs a keystroke sequence instead of performing the bound movements.

• Ctrl+Right outputs [1;5C
• Ctrl+Left outputs [1;5D
• Shift+Left/Right changes panels on Byobu, so those keystrokes are not detected by default
  • The key combination to disable Byobu temporarily, Shift+F12, doesn't seem to go through when using OpenSSH or Putty (with any configuration of keybindings) over Windows
  • Shift+F12 does work on Arch Linux, so Shift+Left outputs [1;2C and Shift+Right outputs [1;2D.

What is the value of the TERM environment variable?

[csolisr]

On the host: screen-256color On the guest: xterm-256color (Arch Linux), N/A (Windows)

[zyedidia]

I think the use of screen-256color is causing the issue. If you are using tmux, consider using tmux-256color instead. Alternatively, you could just run micro with the xterm option set to true.

I managed to make Byobu work properly by forcing the xterm mode, adding the following line to ~/.byobu/profile.tmux:

set -g default-terminal "xterm-256color"
