In an article on tortoiseshell.net, showing how to create a custom footer in
Word 2007 and save it as a Building Block, the author says to type:
=rand(12,5)
to insert a few paragraphs of text. Sure enough, it did.
The text appears to be from a Word Help file.
I've searched high and low for use of the equal sign followed by a function
and argument, to no avail. It's not a field code, for it lacks the curly
braces.
I tried other arguments -- the second seems to specify the number of lines
returned. I'm inclined to try other functions but might just luck out and
find the one that erases all the docx files.
What is this feature?
