Auto-fill feature

Auto-fill feature

Hi,

I am new to using Sheet. I did not find any way of auto-filling a series of cells. For example, I am trying to enter serial numbers in a row and I am not able to drag the cells so that they auto-fill with the series like in MS-Excel. It will be good to have this if it is not already supported. If you already support this, please tell me how I can do it.

Thanks & Regards,
Seshadri
