Hi,
I think you are getting alittle confused with the timeline.
Each individual slide has its own unique time line. If you wish
something to appear after 2 seconds on say the first slide, set
this in the properties for that item, eg graphic to not appear
until after 2 seconds. Alternatively simply grab it on the time
line and slide it left or right.
You can change the length of each individual timeline as
required, in the slide properties (double click the slide in left
hand column)
Hope this helps
