如何清除Dr.Retet IDE中的解释器屏幕？(How can I clear the interpreter screen in Dr. Racket IDE?)

刚开始进入The Little Schemer，并且有一个非常基本的Dr.Racket IDE问题：

我怎样才能清除翻译屏幕？

我如何设置向上箭头来显示以前输入的项目（如Bash中）而不是当前滚动屏幕的行为？

我的搜索空白，可能是因为我不知道这些操作的技术术语。

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

How can I clear the interpreter screen?

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.
