My original question is "Left or right placement of interactive elements on a web page", but only now did I find a place where I think I can find the right people to understand it.
The gist is: is there any natural inclination in right-handed people, when reading a web page, for example, to prefer those interface elements which lead to actions (e.g. "print", "save", "get a link", etc.) to be placed on the right side of the screen and then, to prefer navigational elements (e.g. menus, especially tree-structured category menus) to be placed on the left side, while the preference for content for reading would be in the middle?
That is: navigation (reference stuff) on the left, content (passive perception stuff) in the middle, action elements on the right, all in this manner because of a potential instinct to reach for anything action related with one's right hand.
Is there any research or at least speculation on the subject?
And a follow-up question: if there is such an inclination does it appear to be reverse in left-handed people?
