"Return" or "Back" Button

Good morning.

I would like to know if there is a “return” or “back” button on the Mac version of Scrivener. For example, when you want to make reappear a sentence that has been accidentally deleted. This button is on the toolbar of the Windows version of Scrivener, but I can’t find it on the Mac version.

Thanks.

cmd+z gives you the same function as Alt+backdelete or ctrl+z in Windows
