# - Delete all lines upto the keys definition, and then remove comments
# - Delete all empty lines obtained from above operation, and then remove the tabs at the beginning of lines
# - Look for Keybindings which start with `Key(`, and remove that part then, remove `[` and `]` brackets. After that delete the `lazy` functions.
# - Remove tabs and empty lines, and also closing brackets.
# - Finally remove `"`, and add `+` to the Keybindings.
