Hi Frederick,

That still has the problem of being virtually undiscoverable. There is no way that someone just experimenting with clicking and holding down modifiers would know to press the key to toggle the mode.

Maybe Ctrl+click could work for this after all. Currently Ctrl+click on a selected object will prevent it from drilling in and instead deselect the clicked object.

But Ctrl+click specifically on an unselected object doesn't do anything different than not having Ctrl down.

i'll give it a try and see if that could work ok.
