On a Mac, users can type an em dash by pressing `+ shift + dash`, while an option key press creates an en dash. In Windows, users need to use alt codes or access the emoji keyboard to produce the desired dashes. Microsoft Office apps can also be used to create em and en dashes through specific formatting options. Additionally, text expansion apps like PhraseExpress can be used to quickly insert these symbols into documents. The article concludes by highlighting the importance of understanding when to use em and en dashes in writing.
