The markup on the Board is HTML. You need the sharp angle brackets you get from holding shift and pressing the period and comma keys.
Replacing them with parentheses for this example, the markup is (s)The text you want struck through(/s).
The result, when you replace the parentheses with those brackets, is thus: The text you want struck through.
