I'm new to MathStudio, and LOVING it! Is this the place to ask for help? If so: when you're inputting to MathStudio, what are those left- and right-pointing (boxed) arrows on the left side of the purple input bar? What do they do? Thanks!
Yes, to the first question.
The second: They are cursor keys. They move the input cursor to the left or right. Yes, one can tap and move the cursor, but sometimes for precision it is easier to use the arrow buttons.
