Editing an Action
If you make a mistake when recording an action, don’t panic. Once you’ve stopped recording the action, you can return to a command and double-click it to open the dialog box that contains incorrect settings. Make your changes and close the dialog box. The changes are saved in the action. You can remove a statement from an action by dragging it over the trashcan icon at the foot of the Actions palette.
To add a step, click where it should appear in the action and click the Begin Recording button. Record the missing commands and, when you’re done, click the Stop Playing/Recording button.
