Thanks guys,
Yea, come to think of it, it will be useful for selecting objects that are hidden a bit in a model - good point!
Marc : if you open up the script, there's a section in there with a listing of possible object options that can be selected. Comment out the one that's currently being used and uncomment the one you want - there's one for .getPoints that might work for you. Unfortunately there's no way to add in a quick switching of options without adding in a lot of command line parameters, which would get to be a real mess as far as assigning hotkeys :) .
Anyway, hope it's useful for you!
