    {All,{min,max}}limit the number of possible locators
  • Use Alt+Click on Windows, Cmd+Click on Macintosh, and Ctrl+Alt+Click on Linux.
  • With LocatorAutoCreate->True, any Alt+Click that does not hit an existing locator will cause a new locator to be created at the position of the click. Alt+Click on an existing locator deletes the locator.
  • With LocatorAutoCreate->{min,max}, any Alt+Click that would decrease the number of locators below min or above max will have no effect.
  • LocatorAutoCreate->All specifies that any mouse click that does not hit an existing locator should create a new locator. Alt+Click deletes a locator.
  • When a new locator is added, its coordinates are placed at the end of the list of coordinates for the enclosing LocatorPane or other object.
