I recently installed SSMS 2017 and have been using SSMS for 10 years. In previous versions, CTRL + G was a way to jump to the specified line number. But now another program seems to be overriding this behavior. You will see in these screenshots that I can Go To specified line number from the Edit menu. And that this option seems to be enabled from the Tools -> Options dialog. How can I see what other programs are using this same keystroke combination?
BTW, I have SSMS 2014 on my machine also which I was using before 2017. When I checked SSMS 2014, CTRL + G still works for jumping to line number. So it's only 2017 where it's not working for me.
