Below are some common SQL Server Management Studio keyboard shortcuts that I use on a daily basis to make my SQL life much more productive:

• Ctrl-N…..Open a New Query with the Existing Connection
• Ctrl-Alt-G…..Display Registered Servers
• Ctrl-Alt-T…..Display Template Explorer
• Ctrl-Alt-L…..Display Solution Explorer
• F4…..Display the Properties Window
• F8…..Display Object Explorer
• F7…..Display the Object Explorer Details Window
• Ctrl-F…..Find
• Ctrl-H…..Replace

Enjoy!
