formatting a text written in a string type field in AX 2012?

Is it possible in AX 2012 to find a particular word/words written in a string type field in AX 2012 table or form based on mouse selection. e.g, I have a field named Memo in my table named test. In that field I have a written a text as:

Hello, We need to confirm you that your < mobileNumber > is successfully attached with your account no. < Account >.

Now, if I open a form and select(highlight) a text mobileNumber written in text field using a mouse. Is it possible to do a formatting for the selected word(mobilenumber). I need to clarify that, by formatting I mean to modify the display style of that text(e.g, BOLD, ITALIC, UNDERLINE etc.)

OR, Can I add a text field which have all the formatting options available similar as in below figure.
