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?

Solution 1:

When Magnifier is turned on (it can be minimized), then Ctrl + Alt + I toggles color inversion. Quite handy.

Solution 2:

Yup.

It's Left_Alt + Left_Shift + Print_Screen.

Have fun.

*This command does not invert all colors, it turns on "high contrast" settings, which inverts the colors of some parts of the screen, but not at all, only the main text parts of Microsoft made applications.

Magnifier allows you to invert all colors on the screen like a mac does, but there is no shortcut for that when the Magnifier program is not open.
