Strikethrough versus Track Changes
Manually applying strikethrough is a permanent formatting choice β the line stays until you remove it yourself, and there's no separate record of who added it or when. If you're reviewing a shared document and want changes to be tracked, attributed, and reversible, turning on Track Changes is a better fit, since it automatically shows deleted text with a strikethrough that can later be accepted or rejected.
It works well as a personal productivity marker
Beyond editing, applying strikethrough to a line on a checklist or task list gives a quick, visual sense of what's already done without deleting the text entirely, which keeps a record of everything that was on the list originally.
Frequently Asked Questions
Can I remove strikethrough formatting after applying it?
Yes. Select the same text and click the strikethrough icon again, or uncheck "Strikethrough" in the Font dialog box, to remove it.
Is there a keyboard shortcut to apply strikethrough directly, without opening a menu?
Word doesn't assign a default single-key shortcut to strikethrough, but you can open the Font dialog with Ctrl+D and check the box, or assign your own custom shortcut through Word's keyboard customization settings.
