Where can a get the Greek font used in Latex?

Keys

I don't actually want Latex, but just the Greek font which seems to be pervasively used in papers written with Latex so that I can use it in regular applications. I know I could use Symbol, but the style is slightly different, and other Greek fonts I've seen don't look as good either. I can't seem to find it or even its name. If anyone knows if I can get this in TrueType of PS, I'd appreciate it.
