You can create different custom enhancements and switch between the preview window and the LUT Editor using the Copy and Toggle options on the LUT Editor.
You can also edit the LUT directly in a spreadsheet-style window by selecting Edit Table from the Graph editing tools. To open the LUT for a histogram, click Edit Table in the Graph editing tools area.
Some of the other graph editing tools include: Add Breakpoint, Move Breakpoint, and Delete Breakpoint. These options let you edit the LUT for a specific location on the original image histogram. To show the breakpoints on the curve from the view option list, choose Breakpoints. The Thin Breakpoints option removes excess breakpoints along straight stretches that are associated with a LUT.
