Copy/Move with mouse

[jadO]

Moving a file I can simply drag and drop it, copying it I need to press STRG.
This is the same as in Windows Explorer.
However Windows Explorer has additional feature when you drag and drop with right mouse button then there is a context menu that lets you decide wether you want to move or copy.

This is handy as you have access to everything without the need of the keyboard. Something like that should be incoperated.
