It is a concern of mine to reduce the need for repetitive and inefficient arm movements while working on my art, knowing and using lots of keyboard shortcuts does derive in moving my arm very often to access these functions, sometimes pressing a combination of two or three keys spread apart from each other.
While looking for alternatives to make this process more efficient I came across devices like Clip Studio's own TABMATE ( https://www.amazon.co.jp/dp/B07CNT946X?language=en_US ) or other similar overpriced alternatives. I wanted something that would allow me to access even more functions and found this DIY tutorial: https://www.instructables.com/id/Making-a-powerful-prog... that allowed you to create a quick access macro keypad, I decided to expand on the idea and create a full keyboard out of it with almost all the functions I use on a regular basis and now this is what my set up looks like now, allowing me to access all the functions I could possibly need comfortably with a single press of a button.
I've had such good results with it that I'm posting this for anyone that'll like to try the idea for themselves or customize the idea to their needs, resource links below:
