Right-click is not even necessary. There's a menu bar at the top of the screen, with commands like Finder > Empty Trash.I can't use right click for some reason? Is their a keyboard shortcut? I need to delete stuff from the trashcan.
Also another way to Empty the Trash is Left Click on the Trash icon in the Dock and hold it down. A dialog will pop up and you can click Empty Trash from there also.
