400 CHAPTER 15 Automating Tasks • Press Ctrl (Windows) or Command (Mac OS), and double-click the command. Note: Because an action is a series of commands, you can use the Edit > Undo command to undo only the last command in an action. To undo an entire action, take a snapshot in the History palette before you play an action, and then select the snapshot to undo the action. Setting playback options (Photoshop) Sometimes a long, complicated action does not play properly, but it is difficult to tell where the problem occurs. The Playback Options command gives you three speeds at which to play actions, so that you can watch each command as it is carried out. When working with actions that contain audio annotations, you can specify whether or not the action will pause for audio annotations. This ensures that each audio annotation completes playing before the next step in the action is initiated. To specify how fast actions should play: 1 Choose Playback Options from the Actions palette menu. 2 Specify a speed: • Accelerated to play the action at normal speed (the default). • Step by Step to complete each command and redraw the image before going on to the next command in the action. • Pause For to enter the amount of time Photoshop should pause between carrying out each command in the action. 3 Select Pause For Audio Annotation to ensure that each audio annotation in an action completes playback before the next step in the action is initiated. Deselect this option if you want an action to continue while an audio annotation is playing. 4 Click OK. Editing actions After you record an action, you can edit it in a variety of ways. You can rearrange actions and commands in the Actions palette; record additional commands in an action; rerecord, duplicate, and delete commands and actions; and change action options. Rearranging actions and commands You can rearrange actions in the Actions palette and rearrange commands within an action to change their order of execution. To rearrange actions: In the Actions palette, drag the action to its new location before or after another action. When the highlighted line appears in the desired position, release the mouse button.
