RTF strikeout

I'm working on upgrading an old project with richtext and was wondering whether rtf supports "Strikeout", as it does Bold, Italic, and Underline?

For example, for Bold, I'm using:

-- Create a table for the formatting.
tbFormat = {Bold=true};

-- Set the selected text to bold.
RichText.SetSelectionFormat("RichTextSticky1", tbFormat, true);


Thanks for any info on this!
