A very simple AHK script to remap arrow keys onto WASD only while SAB is the active window.

Save this into a file called SAB_Controls.ahk and run it with AutoHotKey to use.

NOTE: On some machines, tabbing out of the game while holding a direction with this script may cause the direction to still be held when tabbing back in. Simply tapping that direction key after tabbing in will fix this. You'll get used to it.
