Move Line
Move a line throughout your class, but watch out for errors!
Press ⌥⇧↑ (macOS) / Alt+Shift+Up Arrow (Windows/Linux), to move a line up. To move a line down use ⌥⇧↓ (macOS) / Alt+Shift+Down Arrow (Windows/Linux).
This shortcut does not factor in scope. You can move lines in and out of scope.
