> Guacamole's SSH and Telnet terminal emulators do not properly handle modifier key combination {{{}Shift+Tab (Backtab){}}}. Currently, this combination sends the same escape sequences as its unmodified counterparts (Tab sends 0x09, Shift+Tab also sends 0x09), preventing users from using CLI tools that rely on these keyboard shortcuts.
> {{Shift+Tab}} should send the escape sequence {{ESC[Z}} (0x1B 0x5B 0x5A) per standard terminal emulation behavior, as confirmed by testing against AWS SSM web console and standard Linux terminals.
> This impacts user experience when working with interactive CLI tools like:
>  * kubectl/k9s navigation ({{{}Shift+Tab{}}} to move backward through fields)
>  * tmux/screen commands
>  * Claude Code switching between Plan mode and Edit mode
>  * Terminal-based editors and TUIs that use Shift+key combinations
