@Anonymous User ,
This is a great question. Unfortunately, selecting and updating vertices is not very keyboard accessible with our API at the moment. This is good feedback for us to to explore this avenue further. Do you happen to have a use case for this enhancement request that you could share with us? Are you developing an application that would really benefit from this? I understand the accessibility need, we just like to also have real life scenarios to tie to these enhancement requests.
Appreciate your feedback,
Jose
