How to save autoKey settings?
I backup the ~/.config/autokey/data folder to my own .dotfiles folder. Then
Option 1: in a new installation, I softlink my .dotfiles folder to ~/.config/autokey/data.
ln -sf ~/.dotfiles/autokey/data ~/.config/autokey/data
Option 2: Simply replace (Copy and Paste) the default Autokey folder with the content of the backed up folder. Disadvantage is the changes you do will not be automatically saved to your .dotfiles
