Have you ever needed to select all of the blocks that are the same in your drawing?  Typically, you would have to select each one individually, but with the PostalCAD Select Block filter, you can select all of them with ease.

Enter a command that uses the Select object prompt and then right-click.  The PostalCAD Osnap pop-up has several selection filters at the bottom of the list.  Pick the Select block listing to select one instance of a block and the rest will be selected also.

You can also hit the Enter key instead of picking an instance to select from a list of the blocks that reside in your drawing.
