P: same shortcut key for cropping in Camera Raw and Lightroom

As someone who uses both Camera Raw and Lightroom, having the C key as crop tool in CR and compare images in LR (whereas R rotate images in one while being the crop tool in the other) drives me insane daily, and I can't be the only user with this experience.

Assigning shortcut keys ourselves like in PS would be the best but even making both of them C, or R (or whatever third key), do the same thing would be very welcome.
