How to locate blueprint button pressed struct

I have a custom event for mouse click and there is an output option for “Button Pressed” which seems to be a Key struct. For the life of me I cannot figure out how to break this struct so that I can access which button was pressed. The Break Struct pin on the custom event is greyed out and none of the drag-off options seem to allow you to break the struct like you can with the Hit struct. Any help would be great. Thanks.

Generally if Break Struct is greyed out it means the native struct was not marked BlueprintReadWrite if I remember correctly.

Well poop. Do you know if there is another way to find out which mouse button was pressed?

Like this maybe?

Maybe show a bit of code, if that’s not what you mean…
