Changing jumper length

How can I adjust the length of a jumper? I have managed to do this once but completely forgot how I did this.
Thanks in advance.

You click-n-hold the end of the jumper and drag. The outline part that goes dark when you hover over it, not the pad.

Thanks Old_Grey, that worked. I tried this also earlier but for some mysterious reason that did not have any effect but now it does.
