Adobe Captivate gives you the option to lock individual slides. When you lock a slide, all objects on the slide can be viewed but not edited. This feature is useful if you want to send your project to others for review but do not want them to make changes to objects.
You can tell that a slide is locked by looking for the small lock icon. This icon appears below a locked slide in the Filmstrip.
To select multiple slides, press Shift or Control on the keyboard while clicking on the required slides. To select all slides, Edit > Select All.
