Different searches from the address bar

On my old XP machine, I had it set up with a second tool bar at the top
of my screen with an address bar there where I could type in web pages
to open them up, folders to open the folder, or programs, like
notepad.exe to launch the programs. I also somehow had it set up where I
could type "g whatever" and it would search google for "whatever", "d
whatever" and it would search dictionary.com, etc for about 5 different
search engines. It was built into XP and you could choose a one-letter
prefix to select the search engine.

For the life of me, I haven't been able to figure out how to set this
up in Vista. Does anyone know what I'm talking about, what it's called
and/or can point me in the right direction to how to set it up in Vista?
Is it even possible? Thanks.
