I am writing a spreadsheet. On of the features is that if you type something like TOTAL, AVERAGE etc. in the grey margins it calculates the TOTAL (or AVG) of the data. To specify that we should calculate the total, should they type ==TOTAL =TOTAL, or just TOTAL (if they want to specify just the text TOTAL without calculating they always have the option of typing 'TOTAL). https://github.com/gmatht/corro
