Moving Playhead Forward and Backward One Second

I am trying to find a way to move the playhead forward and backward one second. The goal is to have markers throughout the verse, chorus, etc of a song. I would be able to jump between the markers with keyboard shortcuts then have another set of keyboard shortcut to jump around at a one second interval once i'm within the verse or chorus. I know I can shuttle left or right but I need it to be a set time of one second.
