By the way, the brackets have sometimes been buggy.
I would use them to create a document, and when I click on the text within the brackets:
- the new document would contain only part of the word string in the Name and/ or
- every time I click on the text within the brackets, a brand new file is created
This does not happen all the time, but it has happened in the past which is why I use the work around for the most part: create the document I want linked separately and then add it to the document where I wanted the WikiLinks.
