In-cell hover tooltip/cursor change

[rbalza]

Hi everyone, how can I manage to have a tooltip and change it's cursor when hovering an in-cell similar to the attached? Is there any way rather than using the data validation input message?

A data validation input message is only visible when you select a cell, but it does display in a nice tooltip.

A comment (note) will be displayed when you move the mouse pointer over the cell by default, but the user can change this to always display comments.
