About abbreviation forms:
For Esc key - VirtualChar="ESCAPE"
For Up arrow - VirtualChar="UP"
For Down arrow - VirtualChar="DOWN"
For Left arrow - VirtualChar="LEFT"
For Right arrow - VirtualChar="RIGHT"

There is no Insert, Delete, Home, End, Page Up and Page Down keys on your Mac keyboard, so you cannot use them.

Note: I have not tried to create shortcuts with Esc, Up, Down, Left and Right arrows keys on Mac, so I'm not sure if they will work on Mac side.
