So I'm typing in a text and I decide that when I'm done typing in the text I will shrink it. My goal it to make the text go outside of the box while I'm typing it, then shrink it so that the text will look smaller but still fit perfectly inside of the box. However, not seeing my text is a problem. Is there any way that I can reach my goal by doing something else?

If you're using the ‘ask’ block to get the input you can't really do anything but otherwise you'd have to handle every key press yourself. Then you could scroll the text as it is being entered.
