Handy for certain tasksThis is another function that I tend to use when needing to work with paragraphs. I recently came across it again and thought it was fine time to share.
The basic premise is that if the user has some text selected and you want to automate something with regard to the whole paragraphs that have any part selected, then you need something like this.
With all the ifs, switches, etc., this code sure does go marching off to the right, but that is just the way it is. It doesn't have to be pretty, it just has to work.
