It's not something you would put in a field. Focus on nothing is something you send to lose focus on any object that currently has the focuw.
For instance, you have a field which calls a validation function upon closeField. You have a button that saves the information in the field somewhere. At least on MacOS, clicking the button does NOT cause the field to lose focus, because on MacOS a button cannot HAVE the focus. Hence your validation script will never trigger, and you might save bad data.
So in the mouseUp handler of the button, the first line could be focus on nothing. This will trigger the closeField message of the field and execute your validation script.
