This seems to be configuration specific. I don't know who originally set up my SQL Server Management Studio on my PC, but when I am in a query and either highlight the whole query or just the table name in the FROM using Alt+F1, I get a bunch of meta-data on the structure of the table. I get syntax errors highlighting anything else. However, when I highlight something like a function name and use Shift+F1, I am taken to a help screen for the function highlighted. Thus I should get credit for answering Shift+F1, except that as I said it must be configuration specific and highly modifiable from one machine to another.

What is really weird about this is I just went into my Tools-options page and saw that my keyboard settings for the Alt+F1 key are still set to "sp-help", with no other settings for Shift+F1. It seems something somewhere else is over riding the Tools Options Keyboard settings in Management Studio . . . hmmmm!
