You can extend and create a sequence using almost the same procedure as you would when you extend a single exposure. The only differences being that the selected cell must only contain numbers and that you need to press the [Shift] key while pulling down on the selection.
To create a sequence:
|1.||In the Xsheet view, select a cell containing a number.|
|2.||In the selected cell, click on the red arrow on the cell’s right side. Make sure to see the drag down cursor.|
|3.||Hold down the [Shift] key. Make sure a plus (+) sign appears.|
|4.||Pull down the selection box to the desired frame.|
|5.||First release the [Shift] key, then release the mouse button.|
