For a while now my python IDLE has not been working, mostly due to me trying and failing to reconfigure the button assignment to tailor me. Now when i try to open idle it does not open. I tried using some sites for help (http://www.gossamer-threads.com/lists/python/bugs/901999) which had a similar error however, even with a new config file it still wasn't working. Please could I get some help as I need python running on my laptop to do my university coursework. I've attached a file with the error message from cmd.exe and will paste it again;

Under the users .idlerc folder:

C:\Users\Francesca\.idlerc

edit config-extensions.cfg in notepad (don't select always open with)

The code should look like this:

[CodeContext]
visible = False

[ScriptBinding_cfgBindings]
run-module = <Control-Key-F5>

So edited mine to be like this as it was changed to <Control-Alt> and idle was working again!

A crash is when Python stops without a traceback, even when run with somewhere for a traceback to go.  However, I regard it as a bug for IDLE to stop because of a problem in a user.cfg file.  I am not re-opening because this appears to be a duplicate of #11437, which had the same error message with 'up' instead of 'Alt'.
