The REAL issue is that like most other "apps" now, no documentation, you have to figure it out yourself, use Prof. Google or EE.
Too many steps, should be self evident.

You're right, there aren't many sources of keyboard shortcuts. Several years ago (pre-Kindle days), I co-authored a dozen books of tips and shortcuts for Office applications, but they're now out of print. Attached is the book for Word 2003. Much of it is out of date, but 80% of the keyboard shortcuts should still work in the current version. Just-the-tips--man-tm--for-Word-2003.pdf
