In terms of the code, I found that the cursor keys work for controlling the stepper motor. The up/down keys correspond to the x stepper motor, while the y corresponds to the left/right keys. These work through relative moves, but can be switched to absolute moves. All of this was done in the top level of the program.
At the top level of the code, I added a little bit of code to show the users what coordinates they were at as they moved the stepper motors. We can add on to this code at any time in order to display more useful motor coordinates to the user.
