Creating an Exposure Sequence
You can quickly create a sequence with a gesture by holding the Shift key while extending an exposure, or use the Sequence Fill dialog box to create a custom sequence within your selection. While the former is faster, the latter allows you to determine your sequence's hold and increment, to create a backward sequence or to configure it in multiple other ways.

- In the Xsheet view, select a cell containing a number.
- In the selected cell, click the red arrow
on the cell’s right side. Make sure to see the drag down
cursor.
- Hold down the Shift key. Make sure a plus sign (+) appears.
- Pull down the selection box to the desired frame.
- First release the Shift key, then release the mouse button.

- In the Timeline or Xsheet view, select a cell range.
- Do one of the following:
- From the top menu, select Animation > Cell > Sequence Fill.
- In the Timeline view, right-click and select Exposure > Sequence Fill.
- In the Xsheet toolbar, click the Sequence Fill
button (you may have to customize the toolbar to display it).
- Press Ctrl + M (Windows/Linux) or ⌘ + M (macOS)).
The Sequence Fill dialog box opens.
- In the Starting Value field, type the first number in the sequence.
- In the Increment field, type the number by which the drawing number will increase from frame to frame. For example, an increment of 1 gives you: 1-2-3-4; an increment of 2 gives you: 1-3-5-7; and -2 gives you this: 8-6-4-2.
