Avid Add Edit = FCPX Blade = ⌘ B
Avid Export = FCPX Share = ⌘ E
Avid Timewarp/Motion Effect = FCPX Retime = ⌘ R ( ⌥⌘ R to reset)
Avid Select Trim Sides = FCPX Select Edges = [ ] \ (add ^ for video, ⇧ for audio)
Folder =Event is not accurate from a metadata/workflow perspective and would lead a poor Avid editor down precisely the wrong path toward learning the advantages of X over all ofher NLEs. They are fundamentally different in functionality. One is a container with zero awareness of its contents while the other is a live metadata placeholder.
I find it more helpful to map blade to 'B'. I then map the blade-all function to ⌘B, and the Blade tool (which switches the Select Tool to a blade, then you click to blade) to ⇧⌘B. I rarely use the blade tool as a mode, but I blade all the time (obviously). Mapping the function to B is much faster and easier, especially with the new shortcuts of Select Above/Below in 10.3.

Yes, I have preferred shortcuts - mainly to match my normal hodge-podge of Avid / FCP7 / Premiere Pro / Sony 9100 / GVG muscle memory & preference to keeping my right hand free... I felt it was better to state the default command set.
Which has, by and large, had a good deal of thought put into it.
