1. Prior to installing Office 2011, I ran Font Book. No conflicts were noted. All fonts were validated.
2. I then installed Office 2011 and all Office updaters.
3. I then checked Font Book again and discovered about 12-15 “cautions”. So I clicked on the (Auto) Resolve button.
4. Then I started having a myriad of keyboard issues. Clearly, I damaged several fonts when I tried to resolve the cautions noted in Step 3 above.

So I then reverted to a backup volume that did not contain Office 2011 and the fonts it installed, and all is again as it should be.

I would like to reinstall Office 2011 on my Lion volume, but before doing so, I would appreciate your thoughts re what I should do this time to avoid my earlier issues.
