How do I copy file(s) from one folder to another using the mouse and a key, like for example <Left mouse button> + <Shift>. There seems to be no option in mouse configuration. Thank you for help.

You must click on the left on the mouse to select your image and move the mouse to the target folder and then press CTRL.
You will see the arrow of the mouse change.

oops, I did not realize that the (super small) icon does indeed change. thanks franky. ed
