I started using Celtx last week and though it looks good when using celtx, it's impossible to copy it and keep the format I was using. It turns out to be a bunch of words and I don't think the purpose of that software is not being able to copy it.
You'll never be able to copypaste from a script writing program and it keep the formatting haha. That's just not how programming works.
However, you can make a pdf of the script in Celtx and if you want to show it formatted to the forums, you can either upload the script somewhere or you can screenshot the part of the script you'd like to show us.
EXAMPLE:
It depends on what you want to do. After you've worked on your script, you go to the formatting tab and it converts it to a script layout which you can then save as a PDF. You can then copy from within the PDF and paste that into a Word document or Notepad. Be sure to use the paste special and select plain text.I started using Celtx last week and though it looks good when using celtx, it's impossible to copy it and keep the format I was using.
