Simulate "Ease In/Out" (Windows Movie Maker) in Adobe Premiere Elements 3.0 help?

So I've been using Elements 3.0 for a while but I still havent been able to find this option, searched through the video effects but couldnt find it...maybe its under a different name/method?

Ease in/out?? Never heard of that. But then again, Windows movie maker is a cheesy Toy program so that probably don't use the standard actual effect name. I use Vegas Video for editing and it has lots of effects / transistions. Maybe you could describe what the effect or transistion does...
