 As much as possible, the result of executing Python code with IDLE is the
 same as executing the same code in a console window.  However, the different
-interface and operation occasionally affects results.

-For instance, IDLE normally executes user code in a separate process from
-the IDLE GUI itself.  The IDLE versions of sys.stdin, .stdout, and .stderr in the
-execution process get input from and send output to the GUI process,
-which keeps control of the keyboard and screen.  This is normally transparent,
-but code that access these object will see different attribute values.
-Also, functions that directly access the keyboard and screen will not work.
+interface and operation occasionally affects visible results.  For instance,
+``sys.modules`` starts with more entries.

+IDLE also replaces ``sys.stdin``, ``sys.stdout``, and ``sys.stderr`` with
+objects that get input from and send output to the Shell window.
+When this window has the focus, it controls the keyboard and screen.
+This is normally transparent, but functions that directly access the keyboard
+and screen will not work.  If ``sys`` is reset with ``importlib.reload(sys)``,
+IDLE's changes are lost and things li ke ``input``, ``raw_input``, and
+``print`` will not work correctly.
 
 With IDLE's Shell, one enters, edits, and recalls complete statements.
 Some consoles only work with a single physical line at a time.
