Hi there,
I’m posting a new thread on this so that it is easier to find.
You can download a UE4 hotkey list here (enrolling is free):
http://adamsdigitalacademy.teachable.com/courses/unreal-engine-4-quick-tip-tutorials
The volume also includes some quick-tip tutorials on Unreal Engine 4.
Hope you find it useful - in using multiple applications, these can come in handy.
