General Scroll to top op page in one time?

view story

http://androidforums.com – Hi, It took my attention that when i use the facebook/twitter app or different browsers that my phone remembers the last used position of the page and sometimes it's in the middle of the lowest place of the page and i have to scroll down manually to the top of the page that is really annoying. Isn't there a possibility or shortcut to go immediately to the top? I use android 2.3.6 (General)
