I have a number of charts that have 12-20 series each which need to be
changed to different X and Y values. In the Source Data wizard I can
click on the name of a series and then tab through the different
fields and manually type in the changes.

Then I have to go back to the mouse to click on the name of the next
series so I can tab through its fields. I'm wondering if there is a
keystroke that will move on to the next series name. I've tried a
couple of combinations that seemed likely but no luck. Any ideas?
Thanks!
