6.9.9 Setting a Keyword for the PDF

A character string such as the title of a black-and-white document can be used as a keyword for the created PDF file. The keyword is useful when searching the PDF file. Mark a character string to be set as a keyword with a water-based highlight pen so that the character string is completely covered. When you perform a scan, the marked character strings are recognized and set as keywords for the PDF file.

Hereinafter, a line drawn with a water-based highlight pen is referred to as a "marked section", and a water-based highlight pen as a "highlight pen".
