cursor in cell to run instruction on Learn.co-curriculum/python-practice-with-datatypes

[Vajrasamaya]

This lesson has the followig instruction:
"If you haven't already, put your cursor into the cell above and press shift + enter to run the code in the cell. You should see an updated output produced by the .upper() string method."
I tried that but nothing happened. I also tried just shift and just enter, also nothing. FYI, I am using a chromebook which often doesn't work they way another machine might.
Any thoughts?

Nevermind; I figured it out. As usual, human error.
