Cyberix3D - Free Online 3D Game Maker

I want the ability to quick delete or undo something like CTRL + Z to undo or when I select something I can press DEL key to delete it instead of moving my mouse over to undo or to delete...

And I want to be able to select multiple items in the left hotbar that way I can delete more than one item at a time...

We have added your request to the to-do list.
We gave it priority since it's a simple task to develop and a useful feature.
