Hi, Before build 600 there was a nice search function in MetaEditor in the navigator. This came in handy for searching functions (basically anything) and getting the syntax or information in the bottom window. I do not see this in the new build 600+ metaeditor. Is it still there? Here is the old one...

Okay, a few days ago, I opened up a BTC-E account because I knew I could trade on 3:1 margin using Meta Trader 4. So I funded BTC-E with $450. The $450 hit the BTC-E account just fine.
