How To Use Select Next
Select an item in the design as close as possible to the required item, then press the shortcut key N.
Each click of the N button will cause Select to step onto the next item in close proximity to the original picked position, finishing the cycle back at the original selected item. During the cycle the required item will be highlighted.
You can also use the Select Previous command move to the previous selected item. This command is available for assigning to a shortcut key.
