I can go to a specific line number by double clicking in the status bar in Visual Studio. Is there a keyboard shortcut that does the same thing?
Ctrl + G works for me.
If it doesn't work for you, you can always map whatever shortcut you want under Tools | Options | Environment | Keyboard.
EDIT: Yes, as @Brian mentions, the command in this case is Edit.GoTo
I just realised that the default in C# settings for this command is Ctrl + G, whereas in VB Settings, there is no default keyboard short - it's mapped to show the immediate window - strange I think. I swapped the mappings so that the two environment behave the same.
