For example: How do I do "this"?
While you have the editor open, click into the area where you type your content so that you can see the cursor blinking.
(If using a PC) press ALT + F9 or (if using a MAC) press ALT+FN+F9. [important to make sure you click in the text box first and I actually had to use ALT+FN+F9 on my PC laptop].
This will give you access to the editor's menu bar. Select "Format" and then "Strikethrough" and then begin typing.
