How can I clear the interpreter screen in Dr. Racket IDE?

Question

Just starting into The Little Schemer, and have a very basic Dr. Racket IDE question:

1. How can I clear the interpreter screen?

2. How can I set the up arrow to display the previously-typed items (like in Bash) rather than the current behavior of scrolling up the screen?

My searches are coming up blank, possibly because I don't know the technical term for these actions.

Answer 1

Here's how:

1. Click on the "run" button, as you discovered
2. Press Esc + p

And this is the relevant page in the documentation.
