How to change the angle of a brush?

Hiya, I'm trying to adjust the angle of a brush using keyboard shortcuts, I used to be able to use < and > to adjust the angle, but this now just changes the brush type rather than adjusting the angle. I've looked through the keyboard shortcut settings and it doesn't give any option to add a shortcut to adjust the rotation of the angle of a brush, any help will be appreciated, thank you! 🙂
