[Idea] Hidden button "keyboard"

[skrapps914]

Want to add tab and escape keys for some emulators like mame? Here's an idea

a tiny board with corresponding buttons on the inside of the battery compartment cover

You can add tab, escape and any other extra button you need, and when you need to use them, open the battery door, flip it over and it works as a micro button keyboard

Hmm.. Interesting idea!

I did wonder whether you might be able to do something like this using software, maybe through the microcontroller? Have an extra button that acts like a "Shift" key, altering the mappings for the remaining buttons whilst pressed?

This is exactly what I am doing with mine. The code is actually very simple. You just need to set / unset a variable when the button is pressed. Then use if statements to change the mapping based on the variable.
