Inserting lines through words (Strikethrough?)

And for those of you wanting to put a red line through black text in HTML, here is the result. If you try this in the Apple Support Community, it will get set to black strike.

<!DOCTYPE html>

<head>
          <meta charset="utf-8">
          <title>Red Strike-through Example</title>
</head>
<body>
<p>This is a simple test of <strike style="color:red;"><span style="color:black;">line-through</span></strike> in a word using a black span nested inside a red strike.</p>
<p>And, this is another <span style="color:red;text-decoration:line-through"><span style="color:black">line-through</span></span> example using a black span nested within a red, line-through span.</p>
</body>
</html>

How do you insert a horizontal line through a word? I remember once finding a way, but I've forgotten how I did it. I have been seeing soliutions using Word or other word processing programs, but it seems to me that the solution I found was much simplier and easier to use, like using FORMAT. I'm not interested in short-cut methods using keyboard combinations`. I never use them because I find that they're impossible to remember.

Where are you trying to input the strikethrough text? The app you're using should have the feature hidden somewhere.
