Case 1: there is only feeding - you just drag the double-click onto it!

Case 2: you never know EVERYTHING you'll ever want to do with files(objects).
	The number of operations can then get VERY big - how many
	folk round here would like a GREP facility on the Mac - or
	the ability to print an object without opening the damn thing
	and hanging around for needless user interface start-up operations?
	The main flaw in the Mac is the lack of good generic
	operations on objects which test for properties.

NB: reliance on gestures for expressing all actions is not a very good
    idea. Why the hell do you think we developed spoken and written
    language? Note the major inconsistencies in the meaning of
    dragging on the Macintosh.
