Alt+Tab python script help

[johnmacd]

I'm trying to make a button on my remote to handle Alt + Tab with one button. I found this posting that appears to be what I am looking for:
viewtopic.php?f=2&t=685&start=30#p19866

I've changed HID.Button.26 to USB_UIRT.NEC.50863166 which is my button on my remote

But when I add the code into EG as a Python script I get the following error:
Error compiling script.
Traceback (most recent call last):
SyntaxError: invalid syntax (5, line 1)

When I started EG with this script in my tree I got the following error:
Error compiling script.
Traceback (most recent call last) (1582):
File "C:\Program Files\EventGhost\eg\Classes\ActionItem.py", line 121, in SetArguments
self.compiled = self.executable.Compile(*args)
File "C:\Program Files\EventGhost\plugins\EventGhost\PythonScript.py", line 71, in __init__
self.PrintTraceback()
File "C:\Program Files\EventGhost\plugins\EventGhost\PythonScript.py", line 97, in PrintTraceback
treeItem.PrintError("Traceback (most recent call last):")
AttributeError: 'NoneType' object has no attribute 'PrintError'

I'm guessing I'm missing some step in the python process, like to do I need to also add the script to a folder in C:\Program Files\EventGhost\plugins\EventGhost\PythonScript.py

Any ideas what I'm missing or doing wrong?
