Is there a way to remap the keys on a Macbook running macOS 10.15.3, having the right alt key behaving as the left alt key? Apparently there is a difference, because I'm running into the issue where the option (⌥ / alt) keys are not recognised after pressing right-hand option (⌥ / alt) key in NetBeans 11.2.
As I'm disabled, it makes it really hard for me to use the left alt key in combination with the arrow keys, which makes it hard to extend selections with words in NetBeans (and that's something I use a lot). So I hope there is a solution for this other than waiting for the NetBeans developers to fix this.

Make sure to reboot after installing. When starting the tool it will prompt you to set privacy permissions. Do so in the settings:
Now it just a matter of setting the mapping:
