how can I  key into dndCustomAction ?

I would like to handle  alt/ctrl in dndCustomAction method to be able to copy or move in some particular case.
I've tried "this.key" but doesn't works.

Thank you

this.key should work, this.key.control - true if ctrl pressed.

What occurs is that take a long time to init everything ...
I've got 3 treeview with php JSON datas to fillup each and much more javascript to handle everything I need.

It would be nice to have some mechanism to lock the tree meanwhile is not totaly ready.
