"Pad-#" moving Locators

I’ve set up some track markers on a Marker Track.

I know that “Pad-1” and “Pad-2” moves the cursor to the beginning and end of the selection.

However, when I press one of the other pad numbers, say “Pad-5” not only does it move the cursor to the selected marker, but it also sets the left AND right locators to that position.

Any ideas???
