Matrix Keypads are supported. The input is NOT added as HAL Pin to LinuxCNC. Instead it is inserted to Linux as Keyboard direktly.
So you could attach a QWERT* Keyboard to the arduino and you will be able to write in Linux with it (only while LinuxCNC is running!)

# Multiplexed LEDs
Special mode for Multiplexed LEDs. This mode is experimental and implemented to support Matrix Keyboards with integrated Key LEDs. Please provide feedback if u use this feature.

for Each LED an Output Pin is generated in LinuxCNC.
If your Keyboard shares pins with the LEDs, you have to check polarity. The Matrix Keyboard uses Pins as such:
rowPins[numRows] = {} are Pullup Inputs
colPins[numCols] = {} are GND Pins
the matrix keyboard described in the thread shares GND Pins between LEDs and KEYs, therefore LedGndPins[] and colPins[numCols] = {} use same Pins, LedVccPins[] are Outputs and drive the LEDs.
# Quadrature Encoders
Quadrature Encoders require a Library to be installed.
More Info about the used Library can be found here: https://www.pjrc.com/teensy/td_libs_Encoder.html
