Yes, there is a new shortcut key to check a checkbox in Word 2007 and later versions. Here's how you can do it:

1. First, make sure that you have a checkbox control inserted in your document. You can do this by going to the Developer tab (if it's not visible, go to File Options Customize Ribbon and select the Developer tab) and clicking on the Checkbox Content Control button.
2. Once you have a checkbox control inserted, click on it to select it.
3. Now, to check the checkbox using a keyboard shortcut, press the Spacebar key. This will toggle the checkbox between checked and unchecked states.

That's it! You can now use the Spacebar key as a shortcut to check or uncheck a checkbox control in Word 2007 and later versions.
