Undocumented Commands

[Bravo_NPC-Admin1]

Stefan. I found some undocumented commands that aren't explained anywhere. The first one I can think of at the top of my head is onwall2 and onwater2 (?). What are those and how are they used? Also, if you create an NPC that has:
if (playertouchsme) { toweapons /Test; }

You can touch it many times and each time you will get the Weapon named Test. Is that supposed to happen, or is that a bug? Thanks.
