How to create shortcut / accelerated key to close all tab except the focused tab ?

[Admini]

Anytime.

Pressing three keys at the same time, I don't think there's much possibility of a mistouch.

I think you could add the shortcuts as Chrome does not have them, and many users look for these. Besides, many of us prefer Cent Browser over Chrome because it's more feature-rich.

OK, we will consider.
