You'll see two options, "Opacity" and "Fill". With the text layer selected, go up to the top of the Layers palette. Photoshop makes it very easy to do just that. A better solution is to simply hide the text from view while still keeping the layer styles visible.
Since the background color for my document is white, I could just change the color of my text to white, but what if I change the background color later? I'd have to change the text color as well to match the new background.
All I want to see is the stroke outlining it.
Now that I have my first stroke outline around my text, I don't want to see my actual text anymore. The stroke after changing its size and position.
