Well...my questions have had plenty of views, but no answers ....yet I am still playing around with pasteboards...slowly making progress. I **think** this is easy, but have not been able to find a good example. Lets say I have declared a custom UTI in a doc-based application. ...lets call it "com.myCompany.BookMarkUTI". **How** exactly do I add it to the plist ( I am assuming that *that* is indeed where it is added). ( And if the answer is to use the plist editor, which category is it added to)? Thanks in advance.
