I discovered by playing around that
produces the same result as
and, further, that the
\* is essential. This finding suggests that
DisplayForm when inside a string. After more playing around, I found that
produces the same result, but only if you have the bang and the parens, that is, that
\) are both necessary; either construct alone will not work.
Where can I find the documentation for this magic? I don't know what to search for because I don't know what these kinds of constructs are called.
