DIP Switch 4 (Fn key) for Filco Majestouch Convertible 2

16 October 2021

I was confused the other day while trying to understand what the DIP switch 4 on the Filco Majestouch Convertible 2 does. The manual says:

What the heck does top and side mean?

Turns out DIP switch 4 is responsible for positioning the Fn key. Top and side refers to the main and second (Fn) layer of the designated Function key. On a standard ISO laytout, the four bottom-right modifier keys are Alt, Super, Menu, and Ctrl. DIP switch 4 let you change which key to act as the Fn key.
