There are some personalization I did in order to achieve the desired funcionality, like:
- Fn Combinations for multimedia action
- Insert the lights in a somewhat unused space on keyboard
- Adition to four very used keys (calculator, text editor, web browser and file manager)
- Hidden Fn combination (Fn + Win disable the key until the combination is pressed again)
My definition of a classical ABNT2 ISO layout with everything I need.
