Stoopid Question

How do you slow down one or more tracks yet maintain pitch? I'm missing something simple. Thanks

just click on the track, press F2, set the playback rate you wish, tick preserve pitch when changing rate for slow down progression, cut the track where needed and apply different rates on each slice

CTRL+3 CTRL+4 ...

Thanks 

I was stuck on trying to do this using the slider under the tracks instead of looking elsewhere.
