Text Editor
Adafruit recommends using the Mu editor for editing your CircuitPython code. You can get more info in this guide.
Alternatively, you can use any text editor that saves simple text files.
Download the Project Bundle
Your project will use a specific set of CircuitPython libraries and the code.py file, along with a folder full of key configuration files. To get everything you need, click on the Download Project Bundle link below, and uncompress the .zip file.
Drag the contents of the uncompressed bundle directory onto your MACROPAD board's CIRCUITPY drive, replacing any existing files or directories with the same names, and adding any new ones that are necessary.
Inside the macros folder, you’ll likely want to pluck out any macro settings files to discard. They’re prefixed with “mac” and “win”for MacOS and Windows since these systems have different modifier keys. These files are just a starting point for reference…more likely, you’ll start creating your own.
If updating from a prior version of this code, move any key configuration files that you’ve created or edited to a safe place first, so they’re not overwritten or lost, then move them back to the CIRCUITPY/macros folder after updating.

A macro/hotkey program for Adafruit MACROPAD. Macro setups are stored in the
