The verb is something that you usually don't need and it is used with combination of shell execute method. The verb depends on the executable or the document specified in the "process executable" field. The default verb is "open". Other verbs might be "print", "edit" and "explore". By specifying a different verb the "process executable" can be opened, printed, edited or explored.
