I used to be able to use three finger scroll-up to switch between source/header. Since upgrading to Lion, I it just does a regular scroll. Is there any way to get that fea
Given apple took this away (hopefully just for now) the only way I can think of to get this working again would be to install BetterTouchTool[1] and bind the keyboard control - control-cmd-up, ctrl-cmd-down - to the three finger motion. You'd also have to switch the default three finger motion in sys prefs to use four fingers for mission control.
