Hi everyone, maybe the title of my question is not so understandable, so, I will explain a little bit better, the task is to get when i touch in my keyboard the "shift" key an event indicating to my TextBox that I have to put an elevated number, just like the "Superindex" in Microsoft Word, to represent the power of a variable, I need a way to represent this in a text box in WPF. For example, I want to represent this polynomic expression in a TextBox --> X^2+3, but instead having this, I want to have the expression represented in the mathematical way, please, I require your help, thanks, and excuse me for the english, is not the best...

The approach is outlined here:

Something like:

XML

<textblock><run baselinealignment="Superscript" fontsize="12pt">TEST</run>
     E=MC<run baselinealignment="Superscript" fontsize="12pt">2</run>
   </textblock>

Yeah, that's fine, but how can I handle that behaviour with my keyboard, and represent that in a text box, for example: x^2 --> x², I want that when I have the shift key pressed, thanks...

Handle it on Textbox KeyDownPreview I guess, and find out if if Keyboard.IsPressed(Key.ALt) or somehting. It would perhaps be better to make a Checkbox, and when its IsCHecked you send all the text to subscript etc.
