'+' and '-' keys changing temperature and not exposure

Historically in my experience these keys should change exposure values, not color temperature, but I'm at a loss for how to go back to this method; I've tried clicking the exposure slider and using the keys but it doesn't change the mapping of the plus and minus keys.

This is a use case scernario where I've applied my settings and sync'd them across all my flagged images and need to make minor exposure adjustements to each image, but now I have to do it manually with the mouse.
