I know in Visual Studio there is syntax highlighting that matches things like if/for/while statements and highlights it. This is great for small containing statements where it is easy to see but in larger methods that may have multiple return statements or an If..ElseIf..Else..EndIf that goes off screen, it can be difficult to see the bigger picture or tap along to the next section of code. In Visual Studio they have a keyboard command called "Edit.GoToBrace". This seems to be defaulted to "Ctrl + ]" in my system and it allows me to click on a brace and jump to its matching brace. This works in c#, but not in X# currently.
