Is there going to be a uniform keyboard shortcut story for the new notebook UI, or is the idea that every extension configures its own keyboard shortcuts?

If there is something uniform, has the choice of keyboard shortcuts been settled? If yes, is there a place where we can look at the current choices?

We are currently redesigning the keyboard shortcut choices generally inside the Julia extension, and we would like to make sure that the code execution shortcuts we use outside of the notebook UI are aligned with whatever will come via notebook support once it lands.
