2. Place the file under the Python installation path: Python36\lib\idlelib (mine is C:\Python34\Lib\idlelib)

3. Under the same path, locate the Config-extensions.def file

4. Open with Notepad and stick the following code at the end:

[ClearWindow]
Enable=1
Enable_editor=0
Enable_shell=1
[Clearwindow_cfgbindings]
Clear-window=<control-key-l>
