FNable allows you to use your function keys in the apps or games that need them. FNable runs in the background and can quickly change your special keys to function keys. The applications that use function keys are remembered, and everytime you switch to such an application, the function keys will be available. In all other apps the special keys will be available. Of course, you can still use the special keys while your function keys are active, just hold down the FN key when clicking the function keys.
