With native <C-a> & <C-x> keybindings we could do smth like that: 25 => 10<C-a> => 35 & 25 => 10<C-x> => 15.

But while using Boole with <C-a> & <C-x> remappings, this couldn't been reached due to the error.

As for now, I mapped <leader>a & <leader>x for this plugin and it works ok. But it will be really cool to totally replace native mappings.

Could it be fixed? Thanks
