Is there a shortcut to invert colors using the magnifier in Windows 7?

Is there a shortcut to invert colors using the magnifier in Windows 7? I prefer to read documents with color inversion (my eyes don't like white backgrounds). But I found it annoying to click the magnifier and check/uncheck the option. Can I do this with a shortcut?

"If you need a 1 key toggle to flip for viewing images do this:

Download AutoHotKey - free.
Alter the script file in the app to shortcut the windows shortcut to being the context menu button.
Put this code in the script file and put a white sticker over the button. Great for minor visual problems.:

AppsKey::Send ^!{i}

Has saved big hassle fiddling for three keys. If you can spare a button go for it.

All it means is when I press the Appskey, to virtually press Ctrl+Alt+I. Look at documentation to change the key you assign."
