Hello, is posible to add shortcut for "add layer mask"?

I can't find it. Thanks

You can create an action.

I realized that the "Reveal All" and "Reveal Selelction" options as shown in the screenshots are what we are looking for when we want to create a layer mask.
But reveal all will always give you a white layer mask, even if a selection is active, so there is a difference between these two, just in case anyone was wondering! 

and if you always want a black layer mask, that woudl be "Hide All"

THIS is the answer everyone!!! 
New Layer Mask > Reveal All

Thank you!
There was always a way to map a shortcut for this function. We just need to learn the way Adobe words the action lol
