I'm stuck at the point where the input fields have been added to MyCalc in the sandbox, and I need to add a blank line followed by an output field. The tutorial says
"We separated input fields from output field with an empty cell in order to divide input fields from output fields. In order to add it, put caret after inputField's cell and press Enter, then choose constant."
When I put the caret after the inputField's cell and press Enter, I get a new line with another inputField on it:
input <no name>
I see no way of 'choosing constant' at this point.
What is the trick?
