How to remove the box created by "Insert comment box" in DrRacket?

[fuxoft]

After creating the comment box using "Insert / Insert comment box" in the REPL window of DrRacket, I cannot find a way to remove it or otherwise continue with my work. Everything I now type appears inside this box and is not evaluated. I cannot type before or after the box and I cannot delete the box.

Try clicking the empty area below the box. Doing this should position the caret after the box, which allows you to press backspace to delete the box.

That worked, thanks. The are below the box is rather small when the cursor is at the bottom of the window.

Isn't there a way to comment like somewhere else /* .... */ to enclose several lines of code?

#; { … }

#| … |#

Or GUI-style boxes.
