I want to teach myself using hjkl more than using the arrow keys in order to stay on the home row.
Yet my habits are quite strong and I don't even realize that made that hand movement I want to avoid.
In order to break that habit: How can I disable the arrow keys so that I am forced to use the hjkl keys?
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.
