Add keyboard shortcut to execute cell and open new markdown cell about workbooks

[anotherlab]

The problem with using cmd+shift+return (ctrl+shift+return) is while it does open a new markdown cell, it doesn't execute the code in the current cell. I would be happy with a shortcut that converted a code cell to markdown cell (and vice versa).

Nice idea. For reference, our current related keybindings: https://docs.microsoft.com/en-us/xamarin/tools/workbooks/keybindings .

You can do cmd+shift+return to insert a new markdown cell, but right now your cmd+return to evaluate the current cell might still create a new code cell that you might not want.
