ctrl+shift+up/down - not sure what you mean it to do?
In VSCode it adds multiple cursors directly above/below.
In other editors I think it moves (shifts) the current line up or down.
Actually not that important, it also does the same as shift-up/down and I think it's more a convenience feature that one can keep ctrl pressed when it was pressed as ctrl-shift-left/right for word selection and one then presses up/down.
