As a writer, the chances are that you will on occasion be nervous about committing changes to your text. This is what the “Snapshots” feature is for. Before embarking on the editing of a document, you can click on “Take Snapshot” (Ctrl+5) in the Documents > Snapshots menu. You will hear the sound of a camera shutter which indicates that the snapshot has been taken. Let’s try that now…
Once you have taken a snapshot, you can edit your document safe in the knowledge that you can return to the old version any time you so wish. Click on the “Snapshots” button (the one with the picture of a camera on it) in the inspector footer bar to see what I mean (you can also switch directly to the Snapshots pane and have the inspector open if necessary by going to Documents > Snapshots > Show Snapshots). The inspector now shows a list of snapshots at the top, which should consist of the one you took and one I took while writing the first version of this tutorial back in 2006. Clicking on a snapshot in the list reveals its text in the lower part of the inspector. You can restore an older version of your text by selecting the version you want from the list and then clicking on “Roll Back” at the top (at which point, you will be given the option of taking another snapshot of your current version, just in case you forgot).
Snapshots are very useful for keeping old versions of your text around and for checking what you have changed.
