Although there is no keyboard shortcut for striking through text, it’ll only take a few seconds to apply the formatting.

To remove the strikethrough effect, highlight the word or phrase again, and then click the ab icon.

With the word or phrase highlighted, click the small down-arrow on the “Font” panel at the top of the screen. Check the box next to “Double strikethrough. " Click OK.

If you want to remove the strikethrough effect, select the text again, and then tap the ab icon (if you see it) or tap the text formatting icon and select Clear Formatting.
