Have a line of code which goes beyond the screen width? but you need to keep it that way and the only alternative is to scroll all the way to the right?
Well theres good news VS IDE provides a toggle shortcut which will put the line contents beyond the screen width on the next line and back onto the same line

ShortCut Key : - Ctrl + r + r (toggles)
