Sure you can. But the question is for me more why the key is broken. Do we have a broken installer file up? Did something else corrupt the keymap? What happens when you reset Bforartists to factory settings?
Mh, Bforartists uses a different delete method than Blender. We don’t call the delete menu anymore. Which leads me to the second thing that you could try. Switch to Blender keymap, and have a look if delete works there. Here it should call the delete menu quiz in edit mode.
