Formula editor in Keynote is not appearing
I'm using Keynote 7.3.1 on a Mac running OS 10.13.3
In a Keynote presentation I am preparing, I have several charts that display data in tables that I created using the "Edit Chart Data" table that is available whenever you create a chart.
I want to use some simple functions (just addition and subtraction) to generate some of the data in the Chart Data table.
Keynote Help says that when I enter an = sign in a cell, a formula editor will automatically open. But it isn't happening.
Does anyone have any suggestions for why the formula editor isn't appearing?
Thanks!
