current spen button support is: smart snapping ie you select text with pressing the button and hover then release and touch the screen and drag.
looks a bit of a hassle but I like it.
I hope we could have an option in the near future to customize the button like highlight erase etc..
but remember this is the only pdf reader on the playstore to support spen BUTTON.
