Design Doc: Keyboard Accessible Tooltips

[Benjamin Beaudry]

Hi,

In the coming weeks, we intend to start working towards making the tooltips accessible from the keyboard. The goal is to show a control's tooltip when it gains focus from a keyboard command.

I made a design doc and I'd love to hear your thoughts: https://docs.google.com/document/d/1gjciav-KKuj3L524mkg9Z8qFG7WX1NGL2SrPHngNgxA/edit?usp=sharing.

I have already shared this doc with some owners of the area that'll impact, and I now believe it's ready to reach a broader scope.

Cheers!

Ben
