I would want to have Ctrl+ShiftCtrl+Shift as prefix in tmux (because I'm trying to switch from terminator, and the majority of my shortcuts used Ctrl+ShiftCtrl+Shift).
 I tried this in my .tmux.conf :
unbind-key C-b
set-option -g prefix C-S
bind-key C-S send-prefix
It unbind Ctrl+bCtrl+B, but it doesn't rebind it to Ctrl-Shift Ctrl+Shift (actually, the second line alone has the same behavior).
Is there a way to do that, or, as these are two "special" keys, we can't bind them alone ?
Thanks !
