Hi Raffaella,
You don't need a script to do that. You can:
1) Choose "Edit: Go to" menu, and enter: Go to Column=1, go to Row=200. Click OK.
2) Choose "Edit: Go to" menu, and enter: Go to Column=2, go to Row=10000, and turn ON "Extend Selection" check box. Click OK.
That's it. By the way, if you want to run a script, the following command does: worksheet -s 1 200 2 10000
Which one do you prefer?
