mnbvcxzpoiuytrewqlkjhgfdsa
When you have become so beyond bored that you are trying to come up with new combinations of how you can press all of the rows on the keyboard until you find one that hasn't been defined. (Sorry this one's taken)
I've alraeady searched for qwertyuiopasdfghjklzxcvbnm and mnbvcxzlkjhgfdsapoiuytrewq so now I am going to start doing the rows out of order, leading to mnbvcxzpoiuytrewqlkjhgfdsa.
