Style touch is a means of introducing some velocity sensitivity to the style parts- but not drums. They rise and fall together. You can keep the level constant or rise to crescendos or maintain a higher level for a few bars depending on the expression you want and the way you play.
Style Touch is also on the S910, and I find it very useful for certain genres, especially Jazz or Latin.
I'm not sure how many levels of velocity, John, but it appears to be a rather smooth transition from soft to loud.
I believe it goes back to the PSR-2000 at least.
