Playing Requiem with magic mouse. How to throw?!

[WishIhadwindows]

Hello,

I'm playing on an iMac with a magic mouse and I'm at the boxes part, where I need to throw the key box over ledge with the ladder. Previously, I would right click to inspect, so I changed that. The issue with the magic mouse is that I cannot right-click with the left-click on (kill me now) but there isn't even an option in the control settings for throw. Any idea what I can do?

Thanks a bunch!
