Setting modal controls
A modal control pauses an action so that you can specify values in a dialog box or use a modal tool. You can only set modal controls for actions that launch dialog boxes or activate modal tools. If you do not set a modal control, dialog boxes do not appear when you play the action, and you cannot change the recorded values.
A modal control is indicated by a dialog box icon 
to the left of a command, action, or set in the Actions palette. Actions and sets in which some, but not all, available commands are modal display a red dialog box icon 
. In Photoshop, you must be in list mode--not button mode--to set a modal control.
To set a modal control:
- Click the box to the left of the command name to display the dialog box icon. Click again to remove the modal control.
- To turn on or disable modal controls for all commands in an action, click the box to the left of the action name.
- (Photoshop) To turn on or disable modal controls for all actions in a set, click the box to the left of the set name.
