Use the color selection tool to select the green background. By default the Keyer is calibrated to technical Chroma Key Green. Othere shades of green may not key right away.

when I use the chroma key nothing happens. Any ideas?
Select the clip and verify in the Inspector that the effect has actually been applied. Under the Video tab it should be at the top.
If you drag the filter on to your clip – even if there is nothing on the layer below – it should automatically create transparency where you have green and you should see black where the green was, If you have a background clip underneath the clip – say white clouds – then those white clouds should automatically (more or less) replace what was green in your clip.
