For me on a Mac it clears the terminal screen that I used
to launch IDLE and prints a single blank line on the IDLE
shell. (And I have to use "clear" instead of "cls" of course.

A quick Google suggests that printing Ctrl-L (formfeed?) might
be a platform agnostic solution. But that didn't work for me
in IDLE either. I think this is one where the best bet is to go
into the IDLE code and add a Shell submenu to clear screen!
Apparently it's been on the workstack at idle-dev for a long
time but is considered low priority...
