Snap? Can't find it...

Sorry if this is a dumb question - I’ve searched around and just can’t find an answer…

How do I enable snap in LE4?

It’s driving me nuts - I’m editing speech and to have to shift blocks manually after each cut is not much fun. Surely there’s a way to make it that, after an edit, the bits all snap together again?

What part of page 33 in the getting started document do you not understand?

Oh right, I see it now. Thanks for the info.
