Description

A convenient tool that automatically adjusts the function of your keyboard's fn keys based on the application you are using. See at a glance which mode your keyboard is in, thanks to an intuitive icon display in your status bar. When the fn keys act as Apple function keys, one icon is shown, while another icon indicates that the fn keys function as traditional function keys (F1, F2, F3...).

From the developer:

Fluor is a tool that allows you to automatically change the behavior of the keyboard's fn keys depending on the active application. Fluor lies in your status bar and makes you see instantaneously which mode your keyboard is on. A specific icon indicates that the keyboard's fn keys act like Apple function keys, and a different icon means that the keyboard's fn keys act like the good old functions keys (F1, F2, F3...).
