how to use audiotoggledigital in script?

hi
can anyone point me in the right direction to be able to add
"audiotoggledigital"
to a script so that i can toggle it directly from the homescreen?
my idea is to be able to quickly switch from hdmi audio to analog audio so that i can use my wireless speakers for music and whatnot. is there a way to add "audiotoggledigital" to a script so that i can easily switch from 1 source to the other

i am not sure how to add it to a python script, everything i have tried does not seem to work and i do not have a remote or a keyboard that would work, only a laser pointer mouse that i am unable to customize

thanks
