/* * Master list of words to replace. Add as many words to replace as you'd like.
// After making changes to the word replacement dictionary, save (Ctrl+S or whatever hotkey) and then refresh AO3 to see the word replacement changes.
// !! Note that WORDS ARE CASE SENSITIVE !!
// The format is:
// "old word" : "new word",
//
// Example: You want to change all instances of "pancakes" to "waffles" in the fic
// Insert a line of code:
        "pancakes" : "waffles",
// (Remember to keep the comma at the end.)
//
// Alternatively, you can just edit the placeholder code lines with the words you want.
