Need a quick way to see what's on a layer?  Follow these steps to flash the objects from one layer.

1 - Hold down the Shift key and right-click your mouse to open the PostalCAD Osnap menu at the cursor.  Pick the Select Layer listing.  An alternate method would be to type in SLA at the command line rather than using the pop-up menu. 

2 - Pick an item on the layer you want to see flash on the screen or hit the Enter button to pick the layer from a list.

3 - Hold down the Shift key and pick the Flash Previous listing at the bottom of the list.  An alternate method would be to type in FP at the command line rather than using the pop-up menu.

4 - Watch the magic happen as everything on that layer flashes on and off five times in a row.
