I'm trying to bind Control-Tab to a shell function in Bash.I've tried the following things in my .bashrc:bind -m vi-insert -x '\C-\t: some_user_function'bind -m vi-insert -x '\C-TAB: some_user_function'bind -m vi-insert -x '\C-\TAB: some_user_function'But neither work. I couldn't find anything in help bind and man bash either.However bind -m vi-insert -x '\C-x: some_user_function' work so it is clearly a problem with telling bind to recognize the tab key somehow.
How to bind Control-Tab in Bash?
bash;keyboard shortcuts
short: terminals don't do that.long: bash runs in a terminal.  While some provide an escape sequence for shifttab, you're unlikely to find one doing this for controltab unless you specially configure it yourself (using features of a specific terminal emulator).
