Hair cards - Partical system- best method

Heya folks, hope you had a good halloween!

I was follwing a TuT and a usual issue im having is shortcuts appear to have changed ect so makes it hard to follow.

Is there a set method for generating, learning to mask areas an overall go too TuT like the donught one for hair cards? The one i found was by "
THE LUWIZ ART" an it looked fantastic but ye running into non of my hotkeys matching his.
