Create your own raspberry pi Pico macropad something like this one
https://learn.adafruit.com/pico-four-key-macropad/overview

There are two versions
a rectangular one and a curved one

I find the curved one fits my hands better
the switches I used are Kailh CHOC Low Profile like these https://thepihut.com/products/kailh-choc-low-profile-red-linear-key-switches-10-pack

There is some really rough code in code.py that gives you

• 4 sets of keys each programmable (12 in total)
• leds indicating which set is active (binary counting)
• long press switches between sets of macro keys
• sends keys eg ^c
• sends strings eg hello world
• runs functions
• If the 1st long press after booting is key 4 it enters spoof mode

Spoof Mode at random intervals

• moves the mouse
• minimises then restores all windows
• messes with screen brightness
• pops and hides the Win Menu
• ...
