I want to teach myself using hjkl more than using the arrow keys in order to stay on the home row. (I am very aware that one should not use hjkl as the main navigation keys as there are more powerful movement commands available yet this is more about breaking my habits in regards to the arrow keys.)
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.
