Possibility to use wifitoggle?

I’m new to the Omnia and would like to toggle wifi on / off with the button on the front side of it. I know that there are solutions in this forum (like Switch wifi on/off with LED brightness button) but there is one thing I don’t understand: isn’t there a possibility to use the OpenWrt package ‘wifitoggle’ because of the fact that the button on the front isn’t labeled in a mode that it can be used by the script (and so also other scripts) or is this only nowhere documented?
Or is there some documentation about the buttons that I can’t find…?
