Of (OF) access operator
The Dot (OF) access operator is used to access properties of a file (see access docs) or methods of any operand by putting the property/method before the file or operand. See the Dot for more code like syntax.
For example:
findit -w 'name = (name OF parent)'
Will display only the files with the same name as their parent.
findit -w '(length() OF me) > 1024'
Will display only the large files.
