The Verb Properties

Verb

A name of an action. This action can be performed only on the files having an extension the verb is associated with. You can select a verb from the suggested list or you can also add your own verb names.

On the Mac OS X the default verb is "Edit". If you are creating a Mac OS X package, this verb will automatically be associated with the extension, regardless the verb you specify in the list.

Arguments

The command line arguments passed to the program which the extension is associated with, when this verb is selected. This string may contain any values, but can also include special parameters as, for example, %1 - the absolute path to the target file. You can localize this value.

These fields are of Formatted Type and thus they can include references to files, folders and properties.
