Off-topic but this is the first time I've seen waldo used as a verb. It's not in the Urban Dictionary, but from the way you use it I take it that it means "to find the correct thing out of the sea of so many similar things", right?

Waldo Farthingwaite-Jones was born a weakling, unable even to lift his head up to drink or to hold a spoon. Far from destroying him, this channeled his intellect, and his family's money, into the development of the device patented as "Waldo F. Jones' Synchronous Reduplicating Pantograph". Wearing a glove and harness, Waldo could control a much more powerful mechanical hand simply by moving his hand and fingers.
