The F7 key displays details in SSMS 2008. I'm almost positive SSMS 2005 RTM'd with the same funtionality and it was later removed.
I love the F7 key. And I love that it displays details when I highlight something in Object Explorer - which, by the way, no longer displays when I press the F8 key... (grrr) - and then press the F7 key.
As a keyboard guy, I think it would be nice to have the Object Explorer display when I press F8 and Details display when I press F7. I'm sure there's a reason we don't have both in SSMS 2008, even if I don't know what that reason is.
I'm not starting an online petition to have it changed. I'll just work around it.
I sometimes get myself in trouble with function keys.
A few weeks ago I was delivering SSIS training and attempted to demonstrate how you can remove all breakpoints in the Visual Studio 2005 IDE with Ctrl+Shift+F9. I pressed the key combination and it didn't work. Durnit!
I have Camtasia loaded on my presentation laptop. It just so happens Ctrl+Shift+F9 starts/stops recording via the Camtasia plug-in in PowerPoint. I recorded the remainder of the day.
