Adding tomb interactions to other objects

[sms88]

I am in the process of making tombs and I want to create a mod that would allow me to put the "add the ability to add triggers and activated behaviors" and the "hide/unhide" interaction to other objects. I am new, but I have some minor modding experience with creating simple XML edits and have read the pure scripting and object modding tuts. My problem is that I cannot find the quoted interactions. I would appreciate some help on this, because I want to make tombs with more variety.

I'd also be interested to see if anyone can locate that bit of code. I'd love to be able to place an object over hidden stairs, and then 'hide' the object when the stairs are 'unhidden'. I've got too many other projects going on to go diving for this right now, but it is on my wishlist.

Hopefully, someone else will get to it first. ;)
