Não há como imitá-lo exatamente, mas aqui está uma solução alternativa
Edit the keyboard to allow you to set Ctrl-A to do the same thing as Ctrl-Backspace.
Ctrl-Backspace navigates to the current cell and allows you to continue to use your Tab key for right movement, and leaving the Enter key to take you down a row and back to where you started using the Tab key.
Ctrl-Backspace however isn't an easy Keyboard short-cut or at least it isn't for my hands, so I added Ctrl-A to do the same thing. A is right next to the Tab key so it's a fairly fast keyboard click.
