Hi Thomas, sorry no there isn't any way currently to do that type of selection, there isn't any scripting interface to access the control point selection.

You can try the Rebuild command though, that may be able to give you a lighter curve. Either set up a keyboard shortcut with Rebuild as the command name, or push the Tab key and type Rebuild and push enter to launch it. You could then try using a somewhat loose tolerance for the rebuild to get fewer points, try something like 0.02 or 0.05 .
