I'm an Excel2013 newbie, arrive from years of old Excel and LibreOfficeCalc and i find too difficult to work with the Modern UI.

Now I encountered two difficult:
1) where is the setting to set the distance between the cell's edge and it's content?
2) when I wrote a number (or a date) in a cell and I dragged the the edge of it all the new cells were filled of consecutive new value.
Eg.: the value of first cell is 1 and after the dragged the other cells were automatic filled with 2, 3, 4 and so on but now doesen't work. How does it work?

Tks in advance for help!
a.k.a. Tato
