First steps with PaperJS. I realized this sketch and this video to describe the issue. As you can see in the video, drawing, for example, three items, and moving over them to select one and pressing the "d" key on keybord, it is possible to remove just the last added and selected item, but not the previous ones. If you start from the first or second item of the three added, the alert is not even triggered.
The wanted beaviour would be instead to select the event.item.selected
(moving on it with the mouse) and remove just the selected one by clicking the "d" key on keyboard.
Thank you for your help
