O tmux agora tem as seguintes opções:
c0-change-interval interval
c0-change-trigger trigger
Você pode definir valores para estes, o que tornará ^ C e amigos mais fáceis de digitar. Veja man tmux
:
These two options configure a simple form of rate limiting for a pane. If tmux sees more than trigger C0 sequences that modify the screen (for example, carriage returns, linefeeds or backspaces) in one millisecond, it will stop updating the pane immediately and instead redraw it entirely every interval milliseconds. This helps to prevent fast output (such as yes(1)) overwhelming the terminal. The default is a trigger of 250 and an interval of 100. A trigger of zero disables the rate limiting.
