Missing toggle on Dodge/Burn tool in 2.12

[Ritergeek]

Well, by golly, I do see that instruction in tiny white print at the bottom of the window. Memory has not served me well, but it's not the first time for that. Maybe I have too many apps from the past muddled in, but that's not an obvious place to park tool option instructions. Also, I did not have Tool Options fully extended and did not see those radio buttons. Anyway, thanks for clearing that up!
