Keyboard shortcut to finish entry (i.e. enter)

Need some keyboard shortcut to complete entering an item on a mac. If I enter something quickly and press enter it works well, but if I am editing something existing (a small typo for example) or go into any nuances about the item, it's less obvious how to quickly close out of and complete. I have to mouse over and there is not keyboard shortcut. It would ideally be really easy to just edit the text of an entry without having to open a whole separate screen and then toggle back
