Changing the timeline end

Hi Everybody,

do you know if there is  any method to change the timeline end ?

After adding an audio track and having done a lot of changes to my storyline slide I have to align the end of the timeline with the end of my audio track. Sometimes the End of the other elements goes very far  and I have to drag it back wasting a lot of time until it reaches the end of the audio track.

Do you have some tip on this ?

I hope it's clear :)

Thanks a lot,

Mauro
