Reproduction Steps: 
1. sheets.google.com
2. Either new sheet or open an existing one.
3. Insert a row or column of numbers.
4. navigate to end of that row or column and begin typing a formula with the = sign. Observe how Chromevox alerts a user to begin by selecting a range of cells with the arrow keys.
Expected: A user might be able to select cells with the arrow keys, and pressing space to select or deselect. Alternatively, that announcement would disappear, and a user would know that they would have to manually type in the range of cells.
Actual: A user receives a confusing announcement, and the process outlined does not appear to be accessible. CVox utters the cell that is selected, but unless I am misunderstanding, a user does not have control over what is or is not being selected.
