No shortcuts/hot keys at all?

Hello there, 

today i gave a try the and i was amazed in bad way to see that none of all hot keys i know work, like centring the object with C and align it in the center vertically with E. Also keeps like Control+Page Up for moving the object infront and so on. Without those keys it is useless for me. I am wrong something or the keys really dont work? And if they dont work how is it possible to create such an web app and not implement the keys feature?
