In Word 2000, there was a function that allowed you to replace existing text while typing in new text. To activate this procedure, you had to click on the 'Insert' key and then begin typing in the place where you wanted to replace the text.....it displayed the new text and automatically deleted the previous text....
How do you do this in Office 2010, or is it possible????

Thanks in advance
