DefineF - Version 0.78 Let your function keys cut, copy, paste and click like your mouse. If you find mouse clicking tiresome, this fun tool will allow you to use any of your function keys (F1 thru F10) to act as your mouse clicker. You can also assign unused function keys on your keyboard to accomplish common tasks such as copying, cutting, and pasting with one keystroke! There's also a handy drag-and-drop function that lets you move items in Windows without having to click a mouse.
