Scale command

Hello,

I have a copy of the 2011-2012 SDK and have designed a part. However I can't figure out how to scale the part down. I want to reduce it to 80% and have tried looking on the Features bar or in Insert, Features but there simply isn't a scale button there. There's a Move/Copy command, but no Scale. What am I doing wrong? Tearing my hair out a bit here!

Thanks!
