I've been searching on the net and you have it right. Starting with IE 11
MicroSoft has eliminated createTextRange() as a method for the Body object.
Apparently they found that method presents a security vulnerability. That's
a shame, its a very useful method. I haven't yet figured out alternatives.

I dont know specifically, but IE11 is supposed to have replaced most of the
IE specific methods with HTML5 / JS standard code. I have yet to appreciate
how to obtain a set of methods, events and attributes that any specific
application Classes are able to provide.
Best wishes,
Jonathan
