On a few cameras I own, the exposure compensation dial is around the rewind crank. Moving it requires pressing a button that is on top of the camera, towards the rear, just between the dial and the prism. About where your thumb would be if you tried to turn the dial with your left hand. I think this is on my Nikon FE2 and Canon F1N. Is it just me, or is this the absolute worst place to put the release button? I have to press the button with my thumb, which either covers the mark for the dial or puts pressure on the dial making it hard to turn. And with my thumb pressing down, I have no resistance on the backside of my camera so its very hard to turn the dial with my index finger. Maybe I'm just clumsy. Or maybe there is a trick to it that I have not learned. But it certainly feels like I need a third hand just to use the exposure compensation. I think there was an old thread here about badly designed features. This should certainly be added.
