You can also use the number keys 12345567890 to choose a scale for the widget move brush.
If you want to model a smaller area (like you might want to by adding horizontal curves) it is usually best to draw a new object and merge them later, or use the Curvy Map, or convert to mesh and use the surface sculpting tools.
[Older versions of Curvy did have horizontal curves, and it worked a bit like a patch based modeller - but I decided it was too slow and complicated to use]
