A couple of HPL questions

[Froge]

1. Is there a way to figure out which objects in the HPL editor are from other custom stories and which ones aren't? I first noticed this when stuff from Dark Room appeared in the editor; I believe I also have Through the Portal stuff since that's a full conversion mod whose contents I copypasted into my redist folder. Also, were there six different types of keys in the original Amnesia? In my editor there's a Laboratory key, a Study key, a Tomb key, a Rusted Tomb key, a torture chamber key, and a tower key.

2. When finishing a custom story (not full conversion) can you just RAR the folder and upload it onto the Internet, or are there further steps that need to be taken?
