Are there any standards out there for creating a copy (eg. duplicating) of an object using multi-touch? I couldn’t find any with a quick search, so I mocked up a possibility.
The first one is for when you simply want to create a copy of an object. This is analogous to right clicking and choosing “Duplicate” (in OS X).
The second is the same as dragging and object and holding the option key, which creates a duplicate in the drag location (either elsewhere on the desktop, or into a new folder). The first steps are the same (press for a second to get the plus circle), but then instead of tapping the circle, the user drags it and it morphs into a shadow of the object.
Is this natural? Discoverable? Unobtrusive? Does it conflict with other gestures?
