how to do specify all file types in lexima custom rules?

[alexzanderr]

" Please add below in your vimrc
call lexima#add_rule({'char': '$', 'input_after': '$', 'filetype': 'latex'})
call lexima#add_rule({'char': '$', 'at': '\%#\$', 'leave': 1, 'filetype': 'latex'})
call lexima#add_rule({'char': '<BS>', 'at': '\$\%#\$', 'delete': 1, 'filetype': 'latex'})

i saw these beautiful settings which are GREAT! they saved my workflow!

but how do i specify all filetypes? just star *?

Please omit filetype.

" Please add below in your vimrc
call lexima#add_rule({'char': '$', 'input_after': '$'})
call lexima#add_rule({'char': '$', 'at': '\%#\$', 'leave': 1})
call lexima#add_rule({'char': '<BS>', 'at': '\$\%#\$', 'delete': 1})
