[TxMt] jump history

[chad gulley]

i've been using textmate for a few months now.  i'm a vim convert... ;-)

anyway, i've found a replacement for almost everything except vim's  
ability to hit ctrl-o and ctrl-i to go forward and backward in the  
"jump history".  does anyone know how to accomplish this in textmate?   
or maybe just jump back to previous position?  i know bookmarks can do  
basically the same thing...it's just nice to have when you realized  
you forgot to set a bookmark.

thanks.
