Why can't I use cmd + ctrl - b?

[QuarterHeaven]

The "n" and "p" and "f" works very well, and if I change the "cmd + ctrl - b" to other keys like "cmd + ctrl - h" it also works. Just when it was "b", it doesn't work. I tried use "cmd + ctrl - b" as echo, but there's noting on skhd -V. It also works when I use other keys.

I also have this problem. Would appreciate being able to use this shortcut.
