Keyboard Assignments (brake Key)

I am trying to operate the brake key using the keyboard assignments (CTR-S and CTR-SHFT-S), but these just seem to decrease the reverser handle.

Is anyone else managing to move the brake key using the keyboard assignments?

Thanks

 

the default keys are ; and ' respectively(at least in my case)

 

Thanks, I’ll give that a go. I was looking at the keybinds in the options window
