Please provide the options to rename a table aliases or variable namee instead of having to use find/replace. This would be similar to the IntellijIdea IDE Rename feature invoked through the keys Shift+F6 where you highlight a variable, let's say, and then you can rename it.
I wanted to add that some poeple might use very short table aliases such as a, b so using find/replace might not be feasible even with regular expressions.
I find your suggestion very useful.
