Inspiration

I usually have my laptop docked to an external keyboard when working, but the keyboard doesn't have the function keys that the laptop keyboard does. I also often find myself forgetting shortcuts, so I made this so I could work more efficiently.

Challenges

I haven't done any PCB design before, so it took a while to get accustomed to KiCAD, and figure out to import all the necessary libraries and export the board to my CAD program.
