Jordan Rosenthal had a question about FourierTransform.
As part of the question he wrote:
I ran the following code

 FourierTransform[Sign[t], t, w, FourierParameters -> {1, -1}]

and got the following result

  \!\(\(-2\)\ \[Pi]\ DiracDelta[w] +
      2\ \((\(-\(\[ImaginaryI]\/w\)\) - \[Pi]\ DiracDelta[w])\)\)

Is there a better way to copy an output into a posting?
All those backslashes seem to be a bit confusing.

I expect multiple members of the group will answer your question about
Fourier, so I won't get into that. However, I do have a unique perspective
on formatting output for email.

You can format the output using InputForm and the output often comes out
very good. But InputForm is sometimes very annoying. I wrote a package that
formats output like InputForm without the annoying traits. You can download
the package from
The package defines a function called PlainForm.
Load the package, evaluate the following and all your output will be easy to
read in email.
