Move files using mouse only? On Windows, you can drag and drop the file using right mouse button, and choose Copy or Move. Moving a file is a very basic computing need.

I cannot find any way to do that on OS X without using the keyboard. Is it possible to move files using mouse only?
Aren't you still talking about drag and drop? If you are trying to move something from one Directory in Finder to another, you can drag the file out of the current directory and into the directory on the side bar. For example, if you have text.txt in Documents, and you want to move it to the desktop, you can drag it to Desktop in the sidebar, and it will place the file on the desktop.
