Remote Control

question = """

Given a QWERTY keyboard grid and a remote control with arrows and a “select” button, write a 
function that returns the buttons you have to press to type a certain word. The cursor will always 
start in the upper left at the letter Q.

Example:

$ remoteControl('car')
$ 'down, down, right, right, select, left, left, up, select, up, right, right, right, select'
