How to check if modifier keys are pressed during Drag and Drop?

[Ponjimon]

Is there a way to get whether or not a modifier key (e.g. altKey) is being pressed while dragging an item?

getDropOperation requires to return exactly one allowed drop operation but our use case requires the following:

Check for a certain condition and if the condition is met, return cancel. But now I still want to allow copy OR move for the remaining drop operations. My idea was to check if the altKey is being pressed and if it is, return copy, otherwise return move.

is there a way to achieve this?

Turns out, you can just use allowedOperations[0], nevermind then.
