If you did what I did when you installed CTP 3 of SQL Server “Denali” (which happened when I uninstalled CTP 1 then installed CTP 3) you’ll be in for a rude surprise, a lot of your shortcut keys that you’ve been using for years don’t work any more. This is to say the least VERY annoying, and shouldn’t have ever happened. If you upgrade you won’t have this problem as it’ll take your old shortcut key settings.
It isn’t all that hard to fix, provided that you know what each and every hot key was supposed to be you can go into Tools > Options then Environment > Keyboard > General and reset all the keys that are hosed up.
Or you can download the settings file that I’ve put together that has (I think) all the screwed up hot keys corrected. Safe this file on your computer somewhere and uncompress it, then click on Tools > Import and Export Settings. Run through the wizard (be sure to safe your current settings in case it really screws something up) then import my file. Now all your shortcut keys “should” work as expected.
If you find a shortcut key that I missed please put it in the comments below, or let me know in some other way and I’ll get the file updated.
P.S. I’ve sent a nasty note to some of my SQL Server development team contacts. I’ve also submitted a connect item so that feedback can be publicly collected.
