This project uses the Adafruit ESP32-S3 Reverse TFT board to create a switch interface that cycles through a list of keyboard shortcuts. The screen displays the currently active key and next on the list key. Two mono jacks are connected to the board pins to allow one switch to scan through the list while the other switch sends the key press to the connected computer via USB.

Original code for this project is geared towards access the most utilized keyboard shortcuts for the blockly coding environment. Code may be modified as needed. A customizer web tool is available for adding and removing shortcuts as well as a web app to support low vision users.
