Kinesis Advantage keyboard layout with arrows and brackets layer ("arrows"+"brackets"="abraxas")
kp-layer is great for access to arrows and brackets (see image) lots of extra spare keys for customizing
note: you lose a number pad
note2: I also like f and j as tap-hold shifts but that requires qmk firmware or KMonad software. Stock Advantage2 firmware can't do it.
