Hi Jonathan, keyboard shortcuts have to be carefully implemented so they don’t collide with existing shortucts in other parts of the program (and in other programs). For this reason, they’re generally not user-configurable. However, you can make their commands more accessible by customizing the Ribbon. If you haven’t done this before, you can get an idea about how to do this by looking at these Office 2007 Help articles:

Hope this helps!"

I know it isn't much help but it's somthing!

Sounds like you're having trouble with the default template. To fix it, navigate to C:\Users\YourUsername\AppData\Roaming\Microsoft\Templates and rename "Normal.dotm" to "Normal.dotm.old"

Try reopening Word again, it will recreate a new "Normal" template and thus reset all your styles. If the original was corrupted or whatnot, the new copy should be fine.

Note: Versions prior to Office 2007 are named just "Normal.dot" and under Windows XP the file is located in C:\Documents and Settings\YourUsername\Application Data\Microsoft\Templates
