Hotkey don't work =(

[Davide Giusto]

Hi all.
I'm a really noob. I set my first recalbox station. In FBA libretro all work well but i can't perform hotkey+b to go in retroarch option and deep switch. I just remap keyboard but when i press hotkey+B don't do nothing =(

What can i do?

Sorry for my english
