Honestly, I don’t need those extra number keyboard buttons on the side of my desktop keyboard. It just takes up more space, especially if you don’t know how to use it and you are not an account.
No worries, you can easily chop it off and make it into a usable DIY mini keyboard, there’s virtually no wires between the two pieces so you should be fine.
It happened that I had one spare at home, but alas, it was quite big for my small home workplace. I got inspired by Happy Hacking Keyboard and decided to create something similar. I choose to have version with cursor keys, even if hjkl should be enough for working with THE editor. You can create your own HHK too, see process below.
