Numbers

Use VoiceOver to create formulas and autofill cells in Numbers on Mac
To make calculations using data in your table, you can create a formula using the Formula Editor. VoiceOver speaks the names of functions, definitions and examples for each function, formula errors and more, to make it easier to insert and edit formulas in your spreadsheet.
You can also use autofill mode to quickly fill cells, or a row or column, with the same formula, data or a logical sequence of data — for example, a series of numbers, letters or dates. VoiceOver indicates when you are using autofill mode.
