How to change duration of individual slides in a slide presentat.

[Edgar]

How can I change the duration of an individual slide without going through
the 100 some slides in the "Rehearse Timing" command?

Edgar,
If it is just a slide with no animation, select the slide, then just change
the time next to Automatically after in the slide transition task pane.
If you got animation on the slide and want to retime just one slide, have a
look here:
