basically, it defaults to 0, which is eye5. Going down, -1 is eye4, -2 is eye3 etc. Going up, 1 is eye6, 2 is eye7 etc. Store these into .focuseye, or read off it to see which eye you are using. One cycle later (this is fairly irritating), you can start reading vars off that eye. You can use it as a normal eye by going *.eyef.
