Arpeggio
Yes, Hippie Guy is right. It is called an arpeggio.
An arpeggio on any instrument is just a broken chord (one where the notes are played separately rather than together). On a ukulele (guitar, lute, etc) it is played by plucking the strings separately. It is normally played by playing the 4 strings with 4 separate fingers (thumb, first, middle, ring). It should be played quickly (depending on the speed of the music) but the individual notes should still be heard clearly. It could be played with just the thumb, but this give you less control and it doesn't usually sound the same.
The little arrow at the top means play the strings in ascending order (4th ,3rd ,2nd ,1st). The arrow can be at the bottom and in this case the strings are played in reverse order starting with the 1st (A).
I use this symbol a lot in my arrangements. It can be very effective if not used too much.
Hope this clears up the problem.
