Using undo, redo and history

Any edits you make to your document are stored in the History panel. You can then use this, or perform a gesture to undo. You can also redo an edit which you have recently undone again using a gesture.

Using the History panel, if you undo back to a step in history and you continue editing from that step, you can reinstate your redo history that would otherwise be lost. This might be because you changed your mind or if you made an edit that accidentally removed your redo history. Two branches in the history are created:

a visible new branch containing any new edits.
a hidden branch (viewable via a Cycle future icon) storing the redo history.

It is available to have your document's history saved along with the project file only as long as it remains open, but you can optionally save the document history with a copy for future editing sessions; earlier edits can then be returned to even if the document is closed and reopened.

To undo or redo a change:

Do one of the following:

Two-finger tap on the document to undo your last change. Three-finger tap to redo the last change you undid.
On the History panel, tap one of the entries in the list to jump to that state.
On the History panel, drag the slider left to undo a change, right to redo a change.
Swipe up on the History panel icon to undo a change, swipe down to redo a change.

To return the document to its earliest possible state:

On the History panel, drag the slider to the farthest position to the left.

To reinstate your redo history:

Tap Cycle future at the history step where you want to reinstate your original redo history. This history is hidden 'within' the icon, and will be reinstated on tapping.

To save history with a copy of the document:

From the Home screen, do one of the following:
- Swipe left on the document's thumbnail and tap Save As.
- On the Options menu, tap Save As.
Enable Save history for it to be retained in the copy.
Enter a new file name for the copy.
Tap Save.
Choose your desired cloud storage and (optionally) a directory to save the document to.

To set the History panel preferences:

From the Home screen, tap Settings.
Select the General tab, then swipe the Undo Limit setting to the left to reduce the number of stored changes, right to increase the number of stored changes.
For the Autosave Interval option, swipe to the left to reduce the time interval set (in minutes by default) that the document saves.
