Letter keys don't switch between brushes without using shift.
I can't switch between brushes unless I use the shift key. This just started yesterday after years of using J for the spot healing brush and H for the hand (and other key/brush combos). Now I have to us shift J and shift H. This has slowed my editing work considerably. I'm thinking I have probably executed some key combination to cause this but I can't find anything in the Adobe documentation about it.
