F2 Key Remap
Changing the default behavior of the "F2" is the possibly the most annoying feature Adobe has ever released. I'm not being hyperbolic, there was no reason to remap F2 to the help center when F1 already worked in that way.
Additionally adding second key to the keyboard command to rename reduces the functionality of this program. When I'm editing a PDF, I am constantly editing text making me click "Ctrl+F2" is more effort and goes against common convention.
Couldn't agree more. When is the last time you've used built-in help functionality over entering your problem into a search engine?
