SSMS - Keyboard shortcut CTRL+K, CTRL+C not working

Keyboard shortcuts speed up development tasks in order to get more productive results. I encountered this problem that some keyboard shortcuts stopped working like CTRL+K, CTRL+C is not commenting the selected text, and it seemed unaffected. There could be two possible reasons which may cause this behavior:

• First check if you have any add-ins installed? Perhaps this is the cause of making default shortcuts not working as expected because an add-in has taken over the control.

• Second, check the keyboard scheme under Tools > Options > Environment > Keyboard. In my case, it has been switched to SQL Server 2000 you might try switching it back to Standard.
