I’ve just created a Kali Linux partition on my MacBook Pro. On Mac OS I used Karabiner Elements to remap the right alt key to left arrow because my real left arrow key is broken.
Now I want to do the same thing on Kali. To do so I installed xcape. I tried several commands like
xcape -e "Alt_R=Left" and
xcape -e "Alt_R=leftarrow" but none of them modified the keymapping. I also considered to accomplish the key remapping by modifying the xkb files, but I'm unsure which entries in the files I have to modify. I would appreciate any help on remapping the key.
