True X-Mouse Gizmo
True X-Mouse Gizmo is a very handy mouse enhancement that enables you to automatically copy text that you select to the clipboard (as soon as the left button is released), without the need to first right-click on it and select `copy`. You can then paste the copied text with a single middle button click instead of the traditional right-click/paste method. A small X next to the mouse cursor indicates that your selection has been copied to the clipboard. In addition to more efficient copy/paste operations, True X-Mouse Gizmo also allows for easy switching of windows by sending the currently active window to the bottom when you right-click on the title bar. A tray icon allow you to enable/disable the program as needed. Standalone, no installation.
