Is there a keyboard shortcut or function to view the top cell of the notebook. At the moment I can only find a functionality to scroll the selected cell to top, if so how can I select the top cell without scrolling up?

Press Shift + Home to select the cells from current to first and move the cursor to the first cell.
You can also press Shift + End to select cells from current to last and move the cursor to the last cell.
