I'm still planning on a more ambitious navigation mod, but this is a simple interim change to the existing navigation model that allows you to use the up/down keys to navigate directly to an avatar. This means that if you open your card hand & need to cast a spell that targets the enemy avatar, you can simply hit the up key a couple of times instead of navigating left (through potentially a huge number of cards if you're in a long, drawn out match).
