This is the outcome of what I am looking for: ________/________.

I want an unbroken underline. I want the slash to sit on the line and then
I want the entire area shaded. I can get the unbroken underline by using
tabs and then selecting the section and hit underline and I can set the shash
on the line but then I can only shade the slash. I want both areas on either
side of the slash to be shaded.
