Add keyboard focus support to show cell tooltips
Hi,
We have found that the cell tooltips are not accessible for users who are using screen readers or for users who are solely using keyboard for navigation.
The W3C guidelines are a bit vague, but they do suggest:
A tooltip is a popup that displays information related to an element when the element receives keyboard focus or the mouse hovers over it. It typically appears after a small delay and disappears when Escape is pressed or on mouse out.

Would it be possible to include an option to show cell tooltips when the cell has focus, instead of only when the mouse moves over the cell?
