Thank you for contacting Tesla, I apologize for the delayed response. There is not a backslash button for the Model 3 at this time. However, I went ahead and submitted a feature request for this character to be added to the keyboard options. I cannot promise that this feature will be available, but our team reviews every customer request seriously.

Please let us know if you have any other questions or if we can assist in any way.

Thank you for helping us accelerate the world’s transition to sustainable energy.
