Presenter ‘09 gives you the option of locking the player controls on any slides you choose. On a slide where the controls are locked, learners won't be able to navigate by clicking on the player controls, nor by clicking on slides titles in the sidebar.

Many developers use the locking feature if they've applied on-slide hyperlinks to their slides and they want learners to navigate only by clicking on those hyperlinks, rather than by clicking the player controls or the sidebar.

The lock feature's also handy in situations when you need a learner to view an entire slide, without the option of speeding through it or skipping over it. Keep in mind, though, that since locking disables the player controls, learners won't be able to advance from a locked slide unless you've provided on-slide hyperlinks or set the slide advance behavior to automatic.

In this tutorial, we take a look at how to apply slide locking:

  1. With your presentation open in PowerPoint, click Slide Properties.
  2. Click the Lock column for each slide you want to lock. A little padlock icon will appear in the column.
  3. When you're finished locking slides, click OK.

When you publish, users won't be able to use the navigation controls on the slides you've locked. The seekbar and forward/back buttons will be disabled, and if your player interface includes a sidebar, users won't be able to jump to the slides listed there. The padlock icon appears if the user tries to click on any of these things:
