I sometimes have a large amount of query windows open in SSMS 2008.
Is there a keyboard shortcut to navigate between open query windows? Go to previous/next open query window?
I know there is Ctrl+Tab that allows you to select a query window, but it's only helpful if you have named windows.
A challenge you'll find here is what does "next" really mean? Since you can tear off tabs, split the UI, even move tabs onto different monitors, I think "next" and "previous" lose a little meaning, unless you know what order they were opened in.
Anyway, some solutions, with older versions (based on when the question was asked) left intact:
SSMS 2008
Ctrl+F6 will switch between two most recent tabs. And honestly, Ctrl+Tab / Ctrl+Shift+Tab work like next/previous except you have to hit Tab twice (you can ignore knowing what the name of the tab in the list is).
SSMS 2012
In more recent decades
