This is a rubbish approach to a non-problem. At least it should be a non-problem; all the commands should be on menus, with the shortcut listed there. Then you can learn as few or as many as you feel like.
Obviously Adobe programmers think any sort of GUI is a waste of time. In fact, for editing stuff we don't even need any sort of computer at all. A bar magnet and a magnifying glass to modify bits directly on the disk is all that's required.
Not having a rotatable rear screen is a big PLUS as far as I am concerned.
What is a "rage-finder"? (classic or not).
I like having many buttons and dials. Saves having to dive into too many menus. I would check, however, that the left hand is not gripping (and potentially moving) a number of the controls on the left side of the camera. It looks to me like the left hand fingers would be covering the flash, the motor drive control, and the autofocus control.
An eye-level viewfinder is a must (but can be EVF if that is good enough).
Two other things: the camera must be large enough to grip properly, but it must *not* be heavy. I don't understand why a full-frame film camera (90s and before) weighs so much less than even an APS-C DSLR of today. Weight should be 400gm or so.
