On Movie Maker, how do I adjust the length of clips?

I am used to using an ancient version but decided I needed a new one on my new laptop.

I need to be able to adjust the length of my clips and add transitions but cannot seem to get it to look like this:

I don't know how to get it onto the above setting! I really need to alter the length of my clips and add transitions. Please help!
