// Ethan's script stopped working due to some Wanikani changes. The code below is
// 100% my own, but it closely replicates the functionality of Ethan's original script.
// HOTKEYS:
// "+" - Marks answer as 'correct'.
// "-" - Marks answer as 'incorrect'.
// "Escape" or "Backspace" - Resets question, allowing you to retype.
// SEE SETTINGS BELOW.
