Very briefly, the primary aid is a lift if the inside hip, backed up by the inside leg.
Either method works, and some horses will stay straight when cued with the outside leg. But cuing with the inside leg allows you to sit much quieter in your aids - watch a series of tempis, the horses that change off the inside leg tend to be much straighter, and the rider is not wildly swinging their legs and weight around.
