Change length of a track and slow it down.

[fabiospark]

Let's say I recorded a cover of a song.
To start mixing I import a reference track that is the original of that song.
This original is a little slower than my recorded track and therefore is also a little longer, so:

1 - can I "stretch" the length of my track to match the length of the reference track?
2 - if yes, can I do it just dragging a handle with the mouse?
3 - can I do that with a selection of multiple tracks?

Thanks.

I reply to myself only to save other's people time.

1 & 2 - Yes, I can. Holding down SHIFT drag the beginning or the end of the clip you want to stretch.
3 - Yes, all the selected tracks will be stretched if thear WARP flag is on.

Thanks anyway.
