I want to teach myself using hjkl more than using the arrow keys in order to stay on the home row. And yes, I am very aware that one should not use hjkl as the main navigation keys. Yet my habits are quite strong and I don't even realize that made that hand movement to the arrow keys and I want to unlearn it.
In order to break that habit: How can I disable the arrow keys so that I am forced to use the hjkl or some other navigation method?
As a bonus, it would be helpful if there was a message shown
Dont't use this! yet that it's not mandatory. If they don't work, it will be confusing enough for me to rethink my habits.
