Wow, they couldn't add in any more key combinations to make it even harder?
In Numbers, that key combination does not seem to give me the ability to save as an excel spreadsheet, it just brings up a save as dialog box to save as the current format. I don't have Pages (and I don't feel like spending 20 bucks on an app that doesn't work the way I want it too), so I can't tell if you can save as a word document in that app, or you need to export it
